Muhurtha Chapter 3: The Birth Star and the Birth Moon - Tarabala, Chandrabala & Panchaka Explained

Every election chart in Vedic astrology rests on a tripod of three foundational checks. Before you examine planetary yogas, before you assess the Lagna or the weekday, you must first satisfy three non-negotiable conditions: Tarabala (strength of the constellation), Chandrabala (lunar strength), and Panchaka (five-source energy). If any of these three is unfavourable, the entire election loses its power — no matter how beautiful the rest of the chart looks.

Chapter 3 of B.V. Raman's Muhurtha or Electional Astrology teaches these three pillars with clarity and practical worked examples. This guide expands on his text with step-by-step calculation walkthroughs, reference tables, and commentary to help modern students apply these ancient rules with confidence.

"In fixing auspicious times, apart from the special planetary combinations to be applied for specific purposes, there are three factors which are common to almost all elections and which require the astrologer's most careful attention. They are (a) Tarabala or strength of constellation, (b) Chandrabala or lunar strength, and (c) Panchaka or five-source energy."

Think of it this way: planetary yogas are like the furnishings of a house, but Tarabala, Chandrabala, and Panchaka are the foundation, walls, and roof. Without a sound structure, even the finest furniture is useless. This chapter teaches you how to lay that foundation.

Before you can calculate Tarabala or Chandrabala, you need to know two fundamental facts about the person for whom the election is being made:

• Janma Nakshatra (Birth Star) — the constellation (nakshatra) in which the Moon was placed at the moment of birth. There are 27 nakshatras in the Vedic system, from Ashwini to Revati.
• Janma Rasi (Birth Moon Sign) — the zodiacal sign (rashi) in which the Moon was situated at birth. There are 12 rashis, from Aries (Mesha) to Pisces (Meena).

"The constellation ruling at the time of birth is one's Janmanakshatra or birth star and the zodiacal sign in which the Moon is situated at the time of one's birth is one's Janma Rasi or Birth Moon. These are highly important."

Why the Moon? In Vedic astrology, the Moon is the karaka (significator) of the mind. All our experiences are filtered through the mind. When the cosmic energies flowing through the nakshatras and rashis are harmonious with your birth Moon, your mind is receptive, alert, and capable of good judgement. When they are hostile, the mind becomes agitated, confused, or dulled — leading to poor decisions and unfavourable outcomes.

This is why Muhurtha is inherently personalised. A day that is excellent for one person may be terrible for another, because their Janma Nakshatras and Janma Rashis differ. There is no universally "good" day — only days that are good for you.

Tarabala literally means "star strength." It measures the relationship between your birth nakshatra and the nakshatra ruling on the day of the proposed activity. The calculation is straightforward:

1. Count from your Janma Nakshatra to the day's nakshatra (inclusive of both).
2. Divide the result by 9.
3. The remainder tells you the nature of the day.

The Nine Tara Categories

Notice the pattern: odd remainders (1, 3, 5, 7) are unfavourable; even remainders (2, 4, 6, 8) and 9 are favourable. This makes the rule easy to remember. The favourable stars represent harmony between your birth energy and the day's cosmic signature. The unfavourable ones represent friction.

Worked Example from Raman

"A man born in Aswini elects to undertake a journey on a day ruled by Sravana. Counting from the man's Janma Nakshatra to the one ruling on the proposed day, the number will be 22. This divided by 9 leaves a remainder of 4. This goes under kshema or favourable and hence Tarabala is good."

Let us verify this step by step:

• Ashwini is nakshatra #1. Shravana is nakshatra #22.
• Count from Ashwini to Shravana: 22.
• 22 / 9 = 2 remainder 4.
• Remainder 4 = Kshema = Prosperity. Tarabala is good.

The 27 Nakshatras: Quick Reference

Since there are 27 nakshatras and the Tara cycle repeats every 9, each nakshatra appears in three Paryayas (cycles). The crucial teaching is that the evil of unfavourable Taras diminishes with each cycle:

In the second cycle, the evil is not evenly distributed but concentrated in specific quarters (padas) of the unfavourable stars:

• Vipat (3rd star, 2nd cycle = star 12): Evil only in the 1st quarter
• Pratyak (5th star, 2nd cycle = star 14): Evil only in the 4th quarter
• Naidhana (7th star, 2nd cycle = star 16): Evil only in the 3rd quarter

"Suppose the birth star is Rohini and the day's star is Satabhisha. The day's star counted from birth star comes to 21, or the 3rd in the third cycle. The 3rd is Vipat. But it is said to carry little or no evil."

Let us verify: Rohini is #4, Shatabhisha is #24. Count from Rohini to Shatabhisha = 24 - 4 + 1 = 21. 21 / 9 = remainder 3 = Vipat. But since 21 falls in the third cycle (19-27), the evil is negligible.

The 22nd and 27th Stars: A Clarification

"According to some classical writers, the 22nd and 27th stars are always inauspicious. But our experience is to the contrary. The 22nd is always sadhana and the 27th parama mitra and hence they could be considered as auspicious."

This is an important correction. Some traditional texts single out the 22nd and 27th nakshatras as inherently dangerous (the 22nd nakshatra is sometimes called Vainashika or "destructive"). Raman disagrees based on his practical experience. The 22nd star gives remainder 4 (Kshema/Sadhana category in the 3rd cycle), and the 27th gives remainder 0 (=9, Parama Mitra). By the Tara formula, both are auspicious. Raman sides with the mathematics and his experience over superstition.

Chandrabala means "Moon strength." While Tarabala checks the nakshatra level, Chandrabala operates at the rashi (zodiacal sign) level. The rule is simple:

Why these three houses? In Vedic astrology, the 6th, 8th, and 12th houses are called Dusthanas — houses of difficulty. The 6th brings enemies, debts, and disease. The 8th brings sudden obstacles, hidden dangers, and loss. The 12th brings expenditure, loss, and separation. When the transit Moon falls in any of these positions relative to your birth Moon, your mind is under stress, and any undertaking initiated at that time is likely to encounter these difficulties.

Conversely, when the Moon transits the 1st, 2nd, 3rd, 4th, 5th, 7th, 9th, 10th, or 11th from your Janma Rasi, the Chandrabala is favourable. Among these, the 2nd, 5th, 9th, 10th, and 11th are considered especially strong.

Worked Example: When Both Tarabala and Chandrabala Fail

Raman provides a powerful example of what happens when both conditions are violated simultaneously:

"A person born in Mrigasira (Janma Rasi being Taurus) wants to have his marriage on a day ruled by Bharani which means the Moon will be in Aries. There is neither Tarabala (as Bharani will be Naidhana to Mrigasira) nor Chandrabala (the Moon on the election day falls in Aries which would be the 12th from the subject's Janma Rasi). Hence, the day is most inauspicious."

Let us break this down step by step:

• Tarabala check: Mrigashira is #5, Bharani is #2. Counting from Mrigashira to Bharani going forward through the 27 nakshatras: 5 to 27 = 23, then 27+2 = 25... Actually, we count forward: from #5, the next stars are #6, #7... wrapping around, Bharani at #2 means we count 5,6,7,...,27,1,2 = 25. 25 / 9 = remainder 7 = Naidhana (danger). Tarabala is bad.
• Chandrabala check: Janma Rasi is Taurus. Bharani falls in Aries. Aries is the 12th sign from Taurus (counting Taurus as 1: Taurus=1, Gemini=2,..., Aries=12). Chandrabala is bad.
• Double failure: Both pillars are negative. The day is, as Raman says, "most inauspicious."

Raman also adds an important note about Bharani specifically: it is "condemned for all good work and has to be scrupulously avoided." Some nakshatras carry inherent negative qualities for certain activities regardless of Tarabala calculations. These will be covered in detail in Chapter 4.

Panchaka literally means "group of five." This test combines five different sources of cosmic energy into a single calculation. Raman notes that while Tarabala alone suffices for ordinary matters (short journeys, interviews), Panchaka must be checked for major life events such as marriage, nuptials, and entering a new house.

How to Calculate Panchaka

Add together four numbers:

1. Number of the lunar day (Tithi) — counted from the 1st of the lunar month (1 to 30)
2. Number of the weekday — Sunday = 1, Monday = 2, ..., Saturday = 7
3. Number of the constellation — counted from Ashwini (1 to 27)
4. Number of the Lagna (rising sign) — counted from Aries (1 to 12)

Divide the total by 9. The remainder determines the result:

Again, notice the pattern: odd remainders (3, 5, 7) and zero are good; even remainders (2, 4, 6, 8) and 1 are bad. Five out of nine possible outcomes are unfavourable, making Panchaka a fairly strict filter.

Worked Example from Raman

A person wants to start a business. The election parameters are: constellation = Ashlesha, lunar day = 13th, rising sign = Virgo, weekday = Sunday.

29 / 9 = 3 remainder 2. Remainder 2 = Agni Panchaka (fire risk). The time is not favourable.

The Deeper Philosophy Behind Panchaka

"There are many things, as in medicine, so in astrology, which when properly understood and followed would tend to minimise the chances of evil influences indicated by planets, lunar days, constellations and rising signs, and in all these the idea seems to be to avert the evils which would arise as a matter of fact from the attraction or combination of the subtle influences contained in Time and the chemical changes which arise from the conjunctions and repulsions of various forms of energies, some of which are visible, while many of which are subtle and very mysterious in their nature."

This passage from Raman's grandfather, Professor B. Suryanarain Rao, is remarkable. It frames Muhurtha not as superstition but as a technology for working with subtle energies. The "five sources" in Panchaka represent five distinct energy streams — the tithi (lunar phase energy), the weekday (solar-planetary energy), the nakshatra (stellar energy), and the lagna (horizon-point energy). When these energies combine destructively, we get Mrityu, Agni, Raja, Chora, or Roga Panchaka. When they combine harmoniously, the way is clear.

Raman provides a nuanced set of exceptions. Not every bad Panchaka applies to every type of activity. The key insight is that each Panchaka type is specifically harmful for certain categories of elections:

Raman adds a practical caveat: while these exceptions are logically implied by the classical texts, no authority has explicitly endorsed ignoring a bad Panchaka for unrelated elections. His advice is characteristically prudent:

"As far as possible, it is advisable to avoid the evil of panchaka in general irrespective of its definite bearing on an election. But when a more auspicious day cannot be secured, we can resort to the lesser of the two evils."

This is practical wisdom. In real life, you cannot always wait indefinitely for a perfect election day. Sometimes you must choose the best available option. The Panchaka exceptions give you a framework for making that judgement.

Raman closes the chapter with two important sets of exceptions regarding Tarabala.

Partial Avoidance of Unfavourable Stars

When an otherwise good day falls on an unfavourable Tara, you need not reject the entire day. Instead, avoid only the initial portion of the nakshatra when the negative energy is concentrated:

Note: 1 ghati = approximately 24 minutes.

After these initial ghatis pass, the stigma of the unfavourable Tara "no longer holds good." This exception is meant for urgent situations where delay is impossible.

The Janma Nakshatra Paradox

Your own birth nakshatra (remainder = 1, Janma Tara) is ordinarily considered unfavourable for elections. However, it has a fascinating dual nature:

This list reveals something important about the Janma Nakshatra: activities that connect you to your roots and foundation — land, education, ritual, agriculture — benefit from the "home frequency" of your birth star. Activities that involve conflict, departure, or physical risk are harmed by it. And there is a gender-specific exception: for a woman, marriage on her Janma Nakshatra is favourable (presumably because she is establishing a new "home" and the birth star energy supports that transition).
