Hindu Predictive Astrology Chapter 1: Necessity for the Study of Astrology - A Modern Guide

Why should anyone study astrology? B.V. Raman opens his classic textbook with a passionate defence of Jyotisha — not as blind superstition or fatalism, but as a practical, testable science that has been refined over thousands of years. This chapter sets the philosophical foundation for the entire book and answers the most fundamental question every student faces: Is astrology real, and is it worth studying?

Raman argues that the answer lies not in abstract debate but in practical verification — study the rules, apply them to real horoscopes, and let the results speak for themselves.

Raman begins by acknowledging a fundamental divide: some people accept astrology's validity while others dismiss it outright. He attributes this dismissal to prejudice rather than genuine inquiry.

"Various theories have been set up to discover the influences of planets upon the terrestrial phenomena. While some people admit the intimate relationship that exists betwixt the movements of those 'mysterious intelligences' in the heavens and the fortunes and misfortunes of men... there are others who always deny the existence of any sort of connection between the stars and the inhabitants of this earth."

Writing in 1938, Raman was already confronting what remains the central challenge for astrology students today: the prejudice of those who reject the subject without investigation. His response is remarkable in its clarity and pragmatism. Rather than mounting a defensive philosophical argument, he appeals directly to the scientific method.

"This attitude is due to the fact that they do not approach the subject with an unbiassed and unprejudiced mind. Dispassionate enquiry alone can enable one to appreciate the truth behind any branch of knowledge."

His core argument is straightforward: the final test of any theory is whether it works in practice. Rather than engaging in philosophical debate, Raman urges students to collect horoscopes, study the principles, and verify them against real life outcomes.

"In any field of enquiry, the student will find it useful to remember, it is a major error of the intellect to attempt to oppose prejudices based on a priori arguments to the evidence afforded by facts. The final test of a theory is that it should work satisfactorily in practice. This is the test by which astrological theory should be judged."

Modern students should take this to heart. In an age of internet skeptics and "debunkers," it is tempting to spend energy arguing. Raman's advice is wiser: ignore the critics, do the work, and let your results speak. The person who has predicted 50 life events accurately from 50 horoscopes has no need to debate someone who has never cast a single chart.

"Collect the horoscopes of a number of people of all grades, ranks, temperaments and peculiarities and study them in the light of the principles enumerated in the following pages and then you will really get some precious intellectual food for your mental refreshment and you will be doubtless convinced that astrology is a practical and useful science."

Why this matters for students: This empirical approach — test the rules against real charts — remains the best way to learn astrology today. Don't just memorise rules; verify them with actual horoscopes.

Raman provides a clear definition: astrology is the science of foretelling planetary movements and their effects on human and terrestrial affairs — from individual fortunes to earthquakes and national events.

"Astrology is the science which comprises the foretelling of the regular movements of the planets, the fortunes and misfortunes of men, fates of nations, inundations, earthquakes, plagues, volcanic eruptions, pestilences, and other incidents relating to terrestrial phenomena."

Notice how the Sanskrit names are far more evocative than the Western term. Jyotisha connects astrology to light itself — the fundamental creative force. In Vedic cosmology, light (Jyoti) is the primordial energy from which all manifest creation emerges. By naming the science Jyotisha, the ancient sages positioned astrology not as fortune-telling but as the study of the very source of existence.

Hora Sastra — "the science that treats of Time" — is equally profound. In Hindu philosophy, Time (Kala) is not merely a measurement but a living force, the container and destroyer of all things. The great Bhagavad Gita declares "Kalo'smi" — "I am Time, the destroyer of worlds." To study Hora Sastra is to study the architecture of temporal existence itself, the framework within which karma unfolds.

"In Sanskrit it is called Hora Sastra meaning the science that treats of Time. It is also called Jyotisha or the Knowledge of Light from Jyoti or Light which is the root-cause for all known creation."

Raman argues that planetary influence operates on three planes of human existence:

He draws on observable evidence: the Sun governs seasons and plant growth, the Moon controls tides and affects living organisms. If these two luminaries have such obvious power, it follows logically that other celestial bodies also exert influence.

"The Sun by his daily movements and the change of seasons brings to perfection the embryo in plants and animals and brings about various changes on the earth. The Moon being nearest to the earth exercises much influence on it and as she wanes and waxes rivers swell, the tides of the seas are ruled and the plants and animals affected."

This is the empirical foundation of astrology. Even the harshest skeptic cannot deny the Sun's influence on Earth — seasons, photosynthesis, vitamin D synthesis, circadian rhythms, agricultural cycles. Similarly, lunar influence on tides is a matter of physics, not superstition. Raman's argument is simple: if these two celestial bodies demonstrably affect terrestrial phenomena, why should we assume the others do not?

"No sane brain could ever deny the influence of planets upon man and how they affect, deter and facilitate his future career on the three planes of human existence, viz., physical characteristics, mental peculiarities and spiritual aspirations."

Raman goes further, invoking the concept of a universal subtle power that pervades all matter and mediates planetary influence:

"That a certain subtle power, derived from nature, pervades the entire universe, and the earth we inhabit is also subject to this mysterious and subtle power is evident to all. The various elements, encompassing all matter, are altered by the motions of this ethereal power. The acts of creation (srishti), protection (sthiti) and destruction (laya) are embedded in the womb of the All-Powerful Time and these variations are brought about as a consequence of this subtle power."

This "subtle power" can be understood as analogous to what modern physics calls fields — electromagnetic, gravitational, quantum. The ancients perceived that all bodies in the cosmos are interconnected by invisible forces. Astrology, in this view, is the science of mapping how these forces configure themselves at the moment of birth and how they evolve over the lifetime.

"Thus, it invariably follows, that all bodies in nature, whether animate or inanimate, are subject to the motions of the celestial bodies. Not only those that are already in existence are influenced by the movements and configurations of planets, but also the impregnations and growth and developments of the seeds from which all bodies emanate are moulded by the quantity and quality of these influences at the time of impregnation."

The key insight: Planetary influence operates not just on mature beings but on seeds, embryos, and the formative stages of development. The moment of birth (or germination) captures a particular configuration of cosmic forces that will shape the entity's entire trajectory. This is why the birth moment is so critical in Vedic astrology.

One of Raman's most important points — and one that students must internalise — is the clear distinction between astrology and fatalism.

"Astrology must not be confused with fatalism, witchcraft, palmistry and card-shuffling. It interprets what it conceives to be the future of man as moulded by his previous Karma and indicated by the planetary positions at the time of birth."

The key concept here is that the horoscope is a map of karmic tendencies, not an unchangeable decree. Planets show what is likely based on past karma, but human will and effort can modify outcomes.

"The human will is free to a certain extent and advance knowledge of the future can enable one to mitigate many evils. There is a proverb: 'Fools obey planets while wise men control them.'"

Practical takeaway: When reading a horoscope, never present results as fixed fate. The chart shows tendencies and timing — the individual still has agency to respond wisely.

"By thus knowing the future correctly, man can so create an environment that, he can cope with the adverse periods of his life and alleviate the evils, indicated by the planets to a great extent."

Raman reminds us that many of history's greatest thinkers were also practitioners or advocates of astrology:

The ancient Hebrews called the astrologer Asphe — meaning "the mouthpiece of the star." This reveals how seriously ancient cultures took the role of the astrologer: not as a fortune-teller, but as a translator of celestial language.

"The greatest men of the world believed in and practised astrology. Dante declared it to be 'the highest, the noblest and without defect'. Kepler, Bacon, Pythagoras and Democrates were masters in astrology."

The Kepler example is particularly instructive. Johannes Kepler (1571-1630) is celebrated today as one of the founders of modern astronomy, the discoverer of the laws of planetary motion. What is often forgotten or deliberately obscured is that Kepler was also a practicing astrologer who cast horoscopes for clients and wrote extensive treatises on astrology. He did not see astronomy and astrology as contradictory but as complementary — the mechanics and the meaning of celestial motion. His famous quote, "Astronomy is the wise mother; astrology is the foolish daughter. But what daughter would let her mother starve?" shows his nuanced view: he valued astronomy more highly, but he did not dismiss astrology as worthless.

"It is recorded that Newton was attracted to the study of mathematics and astronomy by the contemplation of an astrological figure of the heavens."

This detail about Isaac Newton is rarely mentioned in physics textbooks. The greatest scientific mind of the modern era began his journey into celestial mechanics through astrology. Newton also spent years studying alchemy and theology — his interests were far broader than the narrow rationalist narrative allows. The point is not that Newton "believed" in astrology in a superstitious sense, but that astrology served as a gateway to rigorous astronomical and mathematical inquiry.

In the book's introduction, Raman explains that Hindu astrological research falls under three major systems:

For students: Start with the Parasari system. It is the most comprehensive, most widely accepted, and the one used throughout this book. Once you have a solid grounding in Parasari, you can explore Jaimini and Tajaka as complementary approaches.

"This science had been cultivated to a high degree of perfection by the Hindus long before the so-called period of authentic history. Their researches may be brought under the following three important divisions: (1) Parasari, (2) Jaimini and (3) Tajaka."

"Almost all astrological books in India are after Parasara who is said to have lived before the dawn of Kali Yuga (more than 5,000 years ago). Even eminent authors and commentators like Varahamihira, Bhattotpala, Venkatesa and others, who have enriched the astrological field by the effusions of their fertile brains, have held Parasara in high esteem and have based all their writings on the principles propounded by him. Thus there is absolutely no ground to doubt the accuracy of the Parasari system."

Parasara is to Vedic astrology what Euclid is to geometry or Patanjali is to yoga — the foundational systematizer whose work defines the field. His Brihat Parashara Hora Shastra is the authoritative text that all later authors reference. When Raman says he follows Parasara, he is aligning himself with a lineage stretching back thousands of years, a transmission of knowledge tested and refined across countless generations.

One of Raman's most crucial points — and one that modern students often miss — is that astrology is NOT purely mechanical. You cannot simply learn the rules, apply them like a computer algorithm, and expect accurate predictions. There is an art to this science.

"Astrology is the most ancient of all sciences. It is not a science like Mathematics, Botany, Zoology, Chemistry or Physics, the study of which requires strict adherence to the world's conventionalities of commonsense reasoning and ordinary logic. Astrology comprehends something higher, mysterious and subtle. It is not a mere appeal to the reasoning faculty of man but it is an appeal to his hidden powers and capacities."

This is a profound statement that sets Vedic astrology apart from purely materialistic sciences. Raman is saying that successful prediction requires activating faculties beyond the rational mind — intuition, subtle perception, perhaps even what yogis call prajna (higher knowing).

"Astrological predictions cannot be simply based upon strict hypothetical principles or vague guesses but a certain amount of intuitive capacity must be brought to bear upon such attempts."

What does this mean in practice? Two students can learn the same rules from the same book. One becomes a mediocre astrologer who mechanically applies formulas. The other becomes a master who sees the living reality behind the symbols. The difference is intuition — the capacity to sense which of multiple contradictory indications will actually manifest, the ability to weigh subtleties that no formula can capture.

"The various rules given for future predictions are merely intended for our guidance and we must substantiate them by recourse to the study and examination of a large number of practical horoscopes."

Notice the word guidance. The rules are not laws in the scientific sense — they are guidelines. The skilled astrologer knows when to apply them strictly and when to bend them based on the unique context of each chart. This discernment comes from experience and intuition, not from memorization.

Raman draws an interesting parallel between astrology and Ayurveda (Hindu medicine), noting their deep historical connection:

"Astrology relies more upon the skill and intuitive capacities of the interpreter than upon complicated rules. It gives a sketch of life. It is a mirror in which one's own figure is clearly reflected. Astrology comprehends the manifestation of a sort of relationship among all objects in nature, animal, vegetable and mineral. It records the interaction of influences of all things, visible and invisible."

"While Ayurveda ranks as an Upaveda, Jyotisha or Astrology is one of the Vedangas. It was not a mere accident that distinguished practitioners of one of these arts were generally proficient in the other also. Cosmos is a unity and knowledge cannot be cut up and confined in rigid water-tight compartments."

This is crucial to understand. In traditional Hindu knowledge systems, Jyotisha (astrology) is classified as one of the six Vedangas — the "limbs" or auxiliary sciences of the Vedas. Ayurveda (medicine) is classified as an Upaveda — a supplementary Veda. Both are sacred sciences, and historically, a Vaidya (Ayurvedic physician) was often also a Jyotishi (astrologer), and vice versa.

Why? Because diagnosis and treatment require understanding not just the physical body but the cosmic timing and the karmic patterns reflected in the birth chart. A skilled Ayurvedic doctor might use astrology to determine:

• Which times of year the patient is most vulnerable to illness (based on planetary transits)
• What constitutional weaknesses are indicated by the birth chart (e.g., Mars in the 6th house indicating inflammatory conditions)
• What herbal remedies align with the patient's planetary chart (each plant has planetary correspondences)
• What auspicious timing to begin treatment or perform surgery (Muhurtha)

Raman's point — "Cosmos is a unity and knowledge cannot be cut up and confined in rigid water-tight compartments" — is a rebuke to modern reductionism. The fragmentation of knowledge into isolated disciplines is a historical accident, not a feature of reality. True wisdom integrates.
