Hindu Predictive Astrology Chapter 17: Key-Planets for Each Sign - A Modern Guide

This chapter is one of the most practically important in the entire book. Once you know the Dasas and Bhuktis operating in a horoscope, you need to know whether those planets are functionally good or evil for the specific ascendant. This chapter gives you that information for all 12 signs, including which planet is the Yogakaraka (the single most auspicious planet) and which planets are capable of inflicting death.

"As soon as the Dasas and Bhuktis are determined, the next step would be to find out the good and evil planets for each ascendant so that in applying the principles to decipher the future history of man, the student may be able to carefully analyse the intensity of good or evil combinations and proceed further with his predictions."

This single opening sentence captures the entire purpose of the chapter. Once you have computed the planetary periods (Dasas and Bhuktis, covered in Chapters 14-16), you must determine whether the ruling planet of a given period is functionally benefic or malefic for that particular ascendant. Without this knowledge, Dasa interpretation is essentially guesswork.

How to use this chapter: Identify the ascendant of the horoscope, look up the key planets below, then apply these results when interpreting Dasas, Bhuktis and transits. This chapter serves as a permanent reference card that every Jyotish student should commit to memory.

In earlier chapters, Raman introduced the concept of natural benefics (Jupiter, Venus, waxing Moon, well-associated Mercury) and natural malefics (Saturn, Mars, Sun, Rahu, Ketu). Beginners often assume that Jupiter's Dasa must always be good and Saturn's Dasa must always be bad. This chapter demolishes that assumption entirely.

The functional nature of a planet depends on which houses it rules from the ascendant. A planet ruling a trine (1st, 5th, or 9th house) becomes auspicious regardless of its natural character. A planet ruling a dusthana (6th, 8th, or 12th house) becomes inauspicious even if it is Jupiter himself. When a single planet rules both a trine and a kendra (1st, 4th, 7th, or 10th), it achieves the extraordinary status of Yogakaraka -- the planet that single-handedly produces yoga (auspicious combinations).

The underlying principle comes from Parasara's dictum: lordship of a trine confers auspiciousness, lordship of a kendra confers strength, and lordship of both confers both. Meanwhile, lordship of the 3rd, 6th, 8th, or 11th house brings functional maleficence regardless of the planet's inherent nature. This is why for Taurus ascendant, Jupiter (lord of 8th and 11th) is evil, and Saturn (lord of 9th and 10th) is the Yogakaraka.

"Saturn is the most auspicious and powerful planet. Jupiter, Venus and the Moon are evil planets. Saturn alone produces Rajayoga."

This statement about Taurus ascendant is perhaps the most striking in the entire chapter. Three natural benefics are declared evil, and the most feared natural malefic is crowned the Yogakaraka. If this does not convince the student that functional nature supersedes natural nature, nothing will.

Aries Ascendant (Mesha Lagna)

"Saturn, Mercury and Venus are ill-disposed. Jupiter and the Sun are auspicious. The mere combination of Jupiter and Saturn produces no beneficial results. Jupiter is the Yogakaraka or the planet producing success."

For Aries, Jupiter rules the 9th (Sagittarius) and 12th (Pisces). Despite the 12th lordship, the 9th house lordship dominates because trinal lordship always overrides dusthana lordship when both are held by the same planet. Jupiter therefore becomes the Yogakaraka. The Sun, as lord of the 5th (Leo), is naturally auspicious as a trine lord.

Saturn rules the 10th (Capricorn) and 11th (Aquarius). Though the 10th is a kendra, the 11th house lordship -- considered a mild dusthana in Parasara's system -- taints Saturn. Mercury rules the 3rd and 6th, both dusthanas. Venus rules the 2nd and 7th, both maraka houses. Note especially that Venus, despite being a maraka lord, "will not kill the native" -- a special protective exemption Raman assigns to certain planets.

Leo Ascendant (Simha Lagna)

"Mars is the most auspicious and favourable planet. The combination of Venus and Jupiter does not cause Rajayoga but the conjunction of Jupiter and Mars in favourable houses produce Rajayoga."

Mars rules the 4th (Scorpio) and 9th (Aries) for Leo -- a kendra and a trine -- making Mars the textbook Yogakaraka. This is one of the clearest Yogakaraka assignments in all of Jyotish. Jupiter, lord of the 5th (Sagittarius) and 8th (Pisces), has mixed lordship: the 5th is a trine but the 8th is the worst dusthana. Jupiter is therefore not purely benefic, but when combined with Mars in favourable houses, the combination of the 4th-9th lord (Mars) and 5th lord (Jupiter) creates Rajayoga.

Saturn rules the 6th and 7th. Venus rules the 3rd and 10th. Mercury rules the 2nd and 11th. All three are functionally evil. However, Saturn "does not kill the native when he has the maraka power" -- another instance of the protective exemption.

Sagittarius Ascendant (Dhanus Lagna)

Mars rules the 5th (Aries) and 12th (Scorpio). The 5th house trine lordship dominates, making Mars the best planet. The Sun, lord of the 9th (Leo), is also auspicious as a trine lord. When Sun and Mars combine, they produce Rajayoga -- the conjunction of the 5th lord and 9th lord, the two trinal lords apart from the ascendant lord itself.

Venus rules the 6th and 11th, both problematic houses, making it the primary evil planet. Saturn, lord of the 2nd and 3rd, is a maraka but "does not bring about death even when he is a maraka" -- yet another protective exemption.

Notice the pattern across all three fire signs: Mars is either the Yogakaraka or the foremost benefic. This makes intuitive sense because Mars has a natural affinity with fire signs -- it rules Aries and is exalted in Capricorn (the 10th sign of the natural zodiac). For fire sign ascendants, Mars consistently rules a trine, which is the source of its functional auspiciousness. Jupiter and Sun also feature prominently as benefics, forming a "fiery benefic trio" across these three ascendants.

Taurus Ascendant (Vrishabha Lagna)

Saturn rules the 9th (Capricorn) and 10th (Aquarius) -- a trine and a kendra -- making it the textbook Yogakaraka. Saturn alone produces Rajayoga for this ascendant. Jupiter rules the 8th (Sagittarius) and 11th (Pisces), two houses that confer maleficence. Venus, the ascendant lord, also rules the 6th (Libra). The Moon rules the 3rd (Cancer). All three natural benefics are functionally compromised.

This is perhaps the most counterintuitive result in the entire chapter: a Taurus native should look forward to Saturn's Dasa and be cautious during Jupiter's or Venus's Dasa. The practical lesson is that Saturn's periods often bring career advancement, spiritual growth, and public recognition for Taurus ascendants, while Jupiter's periods may bring debts, health issues, and unexpected expenses.

Virgo Ascendant (Kanya Lagna)

"Venus alone is the most powerful. Mercury and Venus when combined together cause Rajayoga. Mars and the Moon are evil. The Sun does not kill the native even if he becomes a maraka."

Venus rules the 2nd (Libra) and 9th (Taurus). The 9th house trine lordship makes Venus the most powerful benefic. When Venus conjoins Mercury (the ascendant lord and also 10th lord), you get the union of a trine lord and a kendra lord -- the classic formula for Rajayoga. Mars rules the 3rd and 8th, making it doubly evil. The Moon rules the 11th, which carries mild maleficence.

Capricorn Ascendant (Makara Lagna)

Venus rules the 5th (Taurus) and 10th (Libra) -- a trine and a kendra -- making it another textbook Yogakaraka. Venus combined with Mercury (lord of the 6th and 9th) produces Rajayoga, as the 9th lordship of Mercury contributes the trinal component. Mars rules the 4th and 11th; Jupiter rules the 3rd and 12th; the Moon rules the 7th. All three are functionally inauspicious.

For earth signs, Venus and Saturn dominate as Yogakarakas. Saturn is the Yogakaraka for Taurus, and Venus is the Yogakaraka for both Virgo and Capricorn. Note the striking result for Taurus: Jupiter, Venus, and the Moon -- all three natural benefics -- are considered evil due to their house lordships. This makes earth signs the most dramatic demonstration of the principle that functional nature overrides natural character.

Gemini Ascendant (Mithuna Lagna)

"Mars, Jupiter and the Sun are evil. Venus alone is most beneficial and in conjunction with Saturn in good signs produces an excellent career of much fame. Combination of Saturn and Jupiter produces similar results as in Aries."

Venus rules the 5th (Libra) and 12th (Taurus). The 5th house trine lordship gives Venus its functional beneficence. When Venus conjoins Saturn (lord of the 8th and 9th), the 9th lordship of Saturn activates, and together they produce "an excellent career of much fame." This is a specific practical prediction: Gemini ascendants who have Venus-Saturn conjunctions in favourable signs should expect professional distinction.

Mars rules the 6th (Scorpio) and 11th (Aries), both problematic. Jupiter rules the 7th (Sagittarius) and 10th (Pisces); despite ruling two kendras, Jupiter becomes a Kendradhipati -- a kendra lord who loses beneficence through owning only kendras and no trines. The Sun rules the 3rd (Leo), a dusthana. The Moon, lord of the 2nd (Cancer), is a maraka but "will not kill the person even though possessed of death-inflicting powers."

Libra Ascendant (Tula Lagna)

Saturn rules the 4th (Capricorn) and 5th (Aquarius) -- a kendra and a trine -- making it the Yogakaraka. Mercury, lord of the 9th (Gemini) and 12th (Virgo), contributes through its 9th house lordship. The conjunction of Moon (lord of the 10th, Cancer) and Mercury (lord of the 9th) produces Rajayoga -- the union of a kendra lord and a trine lord.

Jupiter rules the 3rd and 6th, both dusthanas, making it functionally the worst planet. The Sun rules the 11th. Mars rules the 2nd and 7th, both maraka houses, but "Mars himself will not kill the person" -- another protective exemption.

Aquarius Ascendant (Kumbha Lagna)

Venus rules the 4th (Taurus) and 9th (Libra) -- a kendra and a trine -- making it the Yogakaraka. Venus combined with Mars (lord of the 3rd and 10th) produces Rajayoga because the 10th lordship of Mars provides the kendra component and Venus provides the trine. Jupiter rules the 2nd and 11th; the Moon rules the 6th. Both are evil.

For air signs, Venus and Saturn again emerge as the key benefics. Jupiter is consistently evil for all three air sign ascendants due to his lordship of dusthana houses (3rd, 6th, or 2nd/11th). This is a critical lesson: Jupiter, the "great benefic" of natural classification, is functionally harmful for half the zodiac. Relying on Jupiter's natural beneficence without checking functional status is one of the most common errors in Jyotish practice.

Cancer Ascendant (Kataka Lagna)

"Venus and Mercury are evil. Jupiter and Mars give beneficial results. Mars is the Rajayogakaraka (conferor of name and fame). The combination of Mars and Jupiter also causes Rajayoga (combination for political success)."

Mars rules the 5th (Scorpio) and 10th (Aries) -- a trine and a kendra -- making it the classic Yogakaraka. Raman uses the specific term Rajayogakaraka, emphasizing that Mars confers both "name and fame." Jupiter, lord of the 6th (Sagittarius) and 9th (Pisces), derives its beneficence from the 9th house lordship. When Mars and Jupiter combine, the result is "political success" -- a Rajayoga specifically noted for its public and authoritative character.

Venus rules the 4th and 11th; Mercury rules the 3rd and 12th. Both are evil. The Sun, lord of the 2nd (Leo), is a maraka but "does not kill the person although possessed of maraka powers." Mars in combination with Moon or Jupiter in the 1st, 5th, 9th, or 10th houses produces "much reputation" -- a specific house-placement prediction.

Scorpio Ascendant (Vrischika Lagna)

"Jupiter is beneficial. The Sun and the Moon produce Rajayoga. Mercury and Venus are evil. Jupiter, even if he becomes a maraka, does not inflict death."

Jupiter rules the 2nd (Sagittarius) and 5th (Pisces). The 5th house trine lordship makes Jupiter the primary benefic. The Sun rules the 10th (Leo) and the Moon rules the 9th (Cancer). When Sun and Moon conjoin -- which happens every new Moon (Amavasya) -- they unite the 9th and 10th lords, producing a powerful Rajayoga. This makes new Moon births in Scorpio ascendant especially significant for worldly success.

Mercury rules the 8th and 11th; Venus rules the 7th and 12th. Both are evil. Jupiter, even as a maraka (2nd lord), "does not inflict death." However, "Mercury and other evil planets, when they get death-inflicting powers, do not certainly spare the native" -- a stark warning about Mercury's lethal potential for this ascendant.

Pisces Ascendant (Meena Lagna)

The Moon rules the 5th (Cancer) and Mars rules the 10th (Aries) and 3rd (Scorpio, co-ruled). But more importantly, Mars is described as "most powerful." When Mars combines with Moon or Jupiter, Rajayoga results. Saturn rules the 11th and 12th; Venus rules the 3rd and 8th; Sun rules the 6th; Mercury rules the 4th and 7th. Saturn, Venus, Sun, and Mercury are all evil -- an unusually long list of malefics. Mars "himself does not kill the person even if he is a maraka."

For water signs, Mars and Jupiter are the dominant benefics. Mars is the Yogakaraka for both Cancer and Pisces, making it one of the most important planets across all water sign ascendants. Venus and Mercury are consistently evil for all three water signs. This is the mirror image of the fire sign pattern, where Mars was also dominant -- suggesting a deep affinity between Mars and the water-fire axis of the zodiac.

One of the most remarkable and practically valuable features of this chapter is Raman's specification, for most ascendants, of certain planets that will not kill the native even if they acquire Maraka powers. The 2nd and 7th house lords are traditionally considered Marakas (death-inflicting planets), and their Dasas and Bhuktis are examined when assessing longevity. However, certain planets are exempted from this lethal role.

The logic behind these exemptions is not explicitly stated by Raman, but careful analysis reveals a pattern: planets that have a functional connection to both a maraka house and a benefic house (trine or the ascendant itself) tend to receive the protective exemption. The benefic lordship appears to "neutralize" the maraka tendency, preventing the planet from actually bringing death during its period.

This information is extremely useful when determining which Dasa will actually bring about death in a longevity analysis. If the only active maraka planet during a critical period is one of the exempted planets, the astrologer can reassure the native that the period may bring health challenges or financial difficulties (other maraka significations) but is unlikely to prove fatal.

Conversely, Raman makes it clear that planets not on this exemption list will inflict death when they possess maraka powers. For Taurus ascendant, "The native will be killed in the periods and sub-periods of Jupiter, Venus and the Moon if they get death-inflicting powers." For Scorpio, "Mercury and other evil planets, when they get death-inflicting powers, do not certainly spare the native." These are unambiguous warnings.

The following consolidated table summarizes every key finding from Chapter 17. Print it out or bookmark this page -- you will refer to it every time you analyze a horoscope.

Knowing the key planets is only useful when applied systematically. Here is a step-by-step method for using this chapter's information in actual horoscope analysis:

Step 1: Determine the Ascendant. This is the foundation. The same planet (e.g., Jupiter) can be the Yogakaraka for one ascendant and functionally evil for another. Everything flows from the ascendant.

Step 2: Identify the Current and Upcoming Dasas. Using the Vimshottari Dasa system covered in earlier chapters, determine which planet's major period (Maha Dasa) and sub-period (Bhukti) the native is currently running, and which ones are approaching.

Step 3: Classify the Dasa Lord. Using the table above, determine whether the Dasa lord is functionally auspicious, evil, or the Yogakaraka for the given ascendant. A Yogakaraka Dasa is the most favourable period in a person's life; an evil planet's Dasa will bring difficulties proportional to its strength and placement.

Step 4: Check for Rajayoga Combinations. If the Dasa lord is part of a Rajayoga combination for that ascendant, and if the two planets involved are conjoined or mutually aspecting in the birth chart, the Dasa will be exceptionally powerful and productive.

Step 5: Assess Maraka Potential. For longevity questions, check whether the Dasa lord is a maraka (2nd or 7th lord) and whether it falls in the "will not kill" exemption list. If exempted, predict health issues or financial loss rather than death.

Step 6: Factor in Dignity and Placement. A Yogakaraka planet that is debilitated or placed in a dusthana will give reduced results. An evil planet that is exalted or well-placed will give less harmful results. The functional classification sets the direction (good or bad); the strength and placement determine the magnitude.
