What Jyotish is

Jyotish, usually translated as "Vedic astrology", is the Indian system of reading the sky to understand a person's life. It takes the positions of the Sun, the Moon and the planets at the moment and place of your birth and uses them to describe your tendencies, your strengths and difficulties, and the timing of the phases you will go through. It is not fortune-telling in the usual sense. The chart does not fix events, and what you do with the picture is up to you.

The word comes from the Sanskrit root jyoti, which means light or a luminous body. Jyotish is one of the six Vedangas, the subjects that support the Vedas, and stands alongside grammar, metre and etymology in that list. The oldest surviving Jyotish text, the Vedanga Jyotisha, is dated by scholars to around 1000 BCE or earlier.

The classical text most Vedic astrologers still work from is the Brihat Parashara Hora Shastra, attributed to the sage Parashara. The text is long and detailed, and later teachers added commentaries and refinements to it. The tradition has been handed down by generations of practitioners, so it is a living craft and has not stayed frozen in an old book.

Common misunderstandings about Jyotish

Jyotish is often misunderstood, by sceptics and sometimes by its own practitioners. It does not predict fixed events. The chart shows tendencies, strengths, difficulties and timing, and Vedic philosophy holds that karma creates tendencies and not certainties. What you make of those tendencies depends on your choices.

It also has little to do with newspaper horoscopes. Sun-sign columns give a broad mood for a twelfth of the world, while a full chart reading looks at the exact moment and place of your birth. And it is a system with its own rules. Jyotish draws on astronomy, mathematics, philosophy and psychology, and on medicine in its older texts, and a trained Jyotishi works through the chart by method and does not rely on intuition alone.

The three branches of Jyotish

  • Siddhanta (Ganita): the mathematical and astronomical branch. It covers planetary positions, eclipses and the exact timing of celestial events. The classical texts contain detailed methods for calculating these.
  • Hora (Jataka): birth chart interpretation, and the branch most people have in mind when they say "Vedic astrology". Hora reads the Kundli for personality, life themes, relationships, career, health and timing through the Dasha system.
  • Samhita: the astrology of larger events, such as nations, weather, harvests and earthquakes. It reads big transits and eclipses for their effect on groups of people.

The nine Navagrahas

Jyotish works with nine influences called the Navagrahas. Each stands for a particular side of life and character:

  • Surya (Sun): the soul, the father, authority, vitality and self-expression.
  • Chandra (Moon): the mind, emotions, the mother and instinct.
  • Mangala (Mars): energy, will, courage and action, including the ability to protect and to build.
  • Budha (Mercury): intelligence, communication and the power to tell things apart.
  • Guru (Jupiter): wisdom, dharma, abundance, teachers, children and grace.
  • Shukra (Venus): relationships, beauty, pleasure, creativity and harmony.
  • Shani (Saturn): discipline, karma, patience, service and the long result of one's actions.
  • Rahu: ambition, desire, foreign links and the pressure to become something more.
  • Ketu: detachment, past-life karma, spiritual depth and the wisdom of letting go.

How a reading works

A full reading starts with the Janma Kundli, the birth chart drawn for the exact time and place of birth. It uses the sidereal zodiac and the Lahiri ayanamsha. The astrologer then looks at:

  • the Lagna (Ascendant) and its lord
  • the Moon sign (Janma Rashi) and its condition
  • where each of the nine Navagrahas sits among the 12 houses, and how strong it is
  • special planetary combinations (Yogas) that change the general picture
  • the Mahadasha and Antardasha you are running, which show the planet colouring this stretch of your life
  • the main current transits, especially Jupiter, Saturn and the Rahu-Ketu axis

Putting these together gives a reading that is personal to you and grounded in the sky at your birth. Two charts that look alike at first glance often read quite differently once the house lords and the running Dasha are worked through, which is why a reading takes time and cannot be done from the Sun sign alone.
