Muhurtha Chapter 6: On Certain Special Yogas — Siddha Yoga and Amrita Siddha Yoga Explained

After five chapters covering the building blocks of Muhurtha — lunar days, weekdays, constellations, and adverse yogas to avoid — B.V. Raman now turns to the positive side of electional astrology. Chapter 6 introduces Siddha Yogas, special combinations of weekday, lunar day (tithi), and constellation (nakshatra) that make a moment supremely auspicious for beginning important undertakings.

While the previous chapters told us what to avoid, this chapter tells us what to seek. If you can find a day that not only avoids all adverse yogas but also carries a Siddha Yoga, your election gains an extra layer of cosmic support. Think of it as moving from "safe to proceed" to "actively favoured by the heavens."

The chapter is brief in the original text — Raman presents the combinations in a concise, almost tabular manner. But do not let the brevity deceive you. These combinations encode a deep understanding of how planetary energies harmonize through the intersection of three independent timing cycles. In this guide, we will unpack each combination, explain the underlying logic, and show you how to apply them in modern life.

The word Siddha means "accomplished," "perfected," or "proven successful." A Siddha Yoga is therefore a combination that has been proven — through centuries of observation — to yield success when important activities are initiated under its influence.

"When a certain weekday coincides with a certain asterism and a certain lunar day, it becomes specially auspicious for good work. In this chapter, I shall give a few such special combinations which go under the special distinction of Siddha Yogas."

The concept works by recognizing that three independent astronomical cycles — the solar week, the lunar tithi cycle, and the nakshatra cycle — occasionally align in harmonious patterns. When they do, the combined energy is greater than the sum of its parts. It is a form of cosmic resonance.

The Three Cycles

To understand Siddha Yoga, you need to understand the three cycles that must align:

A Siddha Yoga occurs when a specific weekday coincides with specific tithis and specific nakshatras. Not every combination qualifies — only those tested and validated by the tradition are recognized.

Why Do These Combinations Work?

The underlying principle is planetary harmony. Each weekday is ruled by a planet. Each tithi has a planetary resonance. Each nakshatra has a planetary lord. When these three planetary influences are naturally compatible — when they support and strengthen each other rather than conflicting — the resulting moment carries an inherently supportive energy.

Consider an analogy: if you are playing music and three instruments happen to play notes that form a pleasing chord, the sound is more beautiful than any single note alone. Siddha Yoga is the astrological equivalent of a perfectly tuned chord — three independent cycles momentarily aligning in harmony.

From a practical standpoint, you can think of Siddha Yoga as a bonus multiplier. A day that is already free of adverse yogas (no Vishtikarana, no eclipsed Moon, no Panchaka problems) becomes even more powerful when it also carries a Siddha Yoga. It elevates the election from "acceptable" to "excellent."

Raman lists the Siddha Yoga combinations for each day of the week. Each combination specifies which lunar days and which nakshatras must coincide with that weekday. Let us examine each one in detail, with commentary on why these particular combinations are considered harmonious.

Sunday (Ravivara) — Ruled by Sun

"Sunday coinciding with the 1st, 4th, 6th, 7th or 12th lunar day and ruled by the constellations Pushya, Hasta, Uttara, Uttarashadha, Moola, Sravana or Uttarabhadra gives rise to Siddha Yoga."

Monday (Somavara) — Ruled by Moon

"Monday identical with the 2nd, 7th or 12th lunar day and with the constellations Rohini, Mrigasira, Punarvasu, Chitta, Sravana, Satabhisha, Dhanishta or Poorvabhadra produces the same yoga."

Tuesday (Mangalavara) — Ruled by Mars

"Tuesday falling on a day ruled by Aswini, Mrigasira, Chitta, Anuradha, Moola, Uttara, Dhanishta or Poorvabhadra gives rise to Siddha Yoga."

Wednesday (Budhavara) — Ruled by Mercury

"Wednesday coinciding with Bhadra and Jaya and with the constellations Rohini, Mrigasira, Aridra, Uttara, Uttarashadha or Anuradha generates Siddha Yoga."

Thursday (Guruvara) — Ruled by Jupiter

Friday (Shukravara) — Ruled by Venus

Saturday (Shanivara) — Ruled by Saturn

For quick reference, here is a consolidated table of all Siddha Yoga combinations. You can bookmark this table and consult it whenever you need to identify an auspicious day for an important election.

In addition to the detailed combinations above, Raman presents a simpler system that considers only the weekday and the tithi group, without requiring a specific nakshatra. This is an easier-to-apply rule that can be used as a quick check.

"A Friday coinciding with Nanda (1st, 6th and 11th lunar days), Wednesday identical with Bhadra (2nd, 7th and 12th lunar days), Tuesday coinciding with Jaya (3rd, 8th and 13th lunar days), Saturday falling on a Riktha tithi (4th, 9th and 14th lunar days), and Thursday falling on 5th, 10th or 15th (Poorna) lunar days constitute Siddha Yoga."

Notice that Sunday and Monday are not included in this simplified system. This does not mean they cannot have Siddha Yoga — it means that for Sunday and Monday, the more detailed weekday-tithi-nakshatra system from Section 2 should be used.

The Logic Behind These Pairings

Each weekday planet has a natural affinity with a particular tithi group. The underlying principle is that the planet's nature resonates with the quality of the tithi group:

• Venus seeks joy — Nanda tithis are inherently joyful, matching Venus's love of pleasure and beauty.
• Mercury seeks auspiciousness — Bhadra tithis are inherently supportive, matching Mercury's need for favourable conditions to conduct business and learning.
• Mars seeks victory — Jaya tithis are inherently competitive and triumphant, matching Mars's warrior energy.
• Saturn seeks emptiness — Riktha tithis, which are normally considered inauspicious, actually complement Saturn's austere, minimalist nature. What is "empty" for other planets is "pure" for Saturn.
• Jupiter seeks fullness — Poorna tithis represent completeness and abundance, matching Jupiter's expansive, generous nature.

This system is elegant because it reveals a deeper truth: no energy is inherently bad. Even the feared Riktha tithis become productive when paired with the right weekday. It is always about the combination, not the individual element.

Beyond the standard Siddha Yogas, Raman introduces an even more powerful combination: Amrita Siddha Yoga. The word Amrita means "nectar" or "immortal" — this is the nectar of the gods, the elixir of immortality from Hindu mythology. An Amrita Siddha Yoga is therefore the highest grade of auspicious timing, a day so perfectly aligned that it carries almost divine favour.

"Sunday to Saturday respectively coinciding with the constellations Hasta, Sravana, Aswini, Anuradha, Pushya, Revati and Rohini will give rise to Amrita Siddha Yoga."

This system is beautifully simple: each weekday has exactly one nakshatra that produces Amrita Siddha Yoga. No tithi requirement is specified, making it easier to find and use.

Why Is Amrita Siddha Yoga So Powerful?

Notice a pattern in the Amrita Siddha Yoga pairings: in most cases, the nakshatra lord is different from the weekday lord, yet complementary to it. This is not accidental. The Amrita combinations represent the principle of complementary opposites — two energies that, while different in nature, combine to create something greater than either alone.

Consider Saturday-Rohini: Saturn is cold, austere, and slow; Rohini (Moon) is warm, fertile, and flowing. Together they produce enduring growth — like a carefully tended garden that yields abundant harvest precisely because it was cultivated with patience and discipline. This is the "nectar" — the perfect balance of opposing forces.

The exception is Monday-Sravana, where both the weekday and nakshatra are Moon-ruled. Here, the doubling is itself the perfection — the Moon operating at its fullest capacity, in its own day and its own star, creating an unmatched environment for all lunar activities: worship, nurturing, travel, domestic ceremonies, and emotional healing.

Raman closes the chapter with a critical instruction that ties Siddha Yogas to the broader framework of electional astrology:

"The above special yogas can be applied with advantage to important elections and if in addition to the general strength of the day due to a special yoga, the Lagna is also rendered strong, chances of success of the enterprise would be by far the greatest."

This is a vital point. A Siddha Yoga alone is a positive factor, but it reaches its maximum effectiveness when combined with a strong Lagna (ascendant). The ascendant at the moment of election is the chart's anchor — it determines how the day's energy is channelled into the specific undertaking. A Siddha Yoga day with a weak or afflicted Lagna is like having a tailwind but a broken rudder.

Step-by-Step: How to Use Siddha Yoga in Elections

Modern Applications

In contemporary life, Siddha Yoga can be applied to a wide range of important decisions:

• Business launches: Choose a Siddha Yoga day for registering a company, launching a product, or signing a major contract.
• Medical procedures: Non-emergency surgeries and treatments can be scheduled on Siddha Yoga days for better outcomes.
• Real estate: Signing deeds, beginning construction, or moving into a new home.
• Education: Starting a new course, sitting for an exam, or beginning research.
• Travel: Beginning a long journey, especially on a Monday or Wednesday Siddha Yoga.
• Investments: Making significant financial commitments on a Wednesday or Thursday Siddha Yoga.
• Weddings and engagements: Friday Siddha Yoga days are particularly favourable.

Based on the teachings in this chapter and the broader muhurtha framework, we can establish a clear hierarchy for ranking the auspiciousness of any given day. From strongest to weakest:

This hierarchy helps you make practical decisions when you cannot find a perfect day. In real life, you often have constraints — a wedding date that must fall within a specific month, a surgery that cannot wait more than a week. In such cases, aim for the highest level of auspiciousness that is practically achievable, and do not let the perfect be the enemy of the good.
