The Vimshottari Dasha System in Vedic Astrology

Episode 193 features an interview with astrologer Freedom Cole on the vimshottari dasha system, which is a timing technique used in Vedic astrology. In the last episode of the podcast we presented an introduction to a recently recovered ancient time-lord technique called zodiacal releasing, and noted how a number of similar techniques called "dasha" systems are still used in Indian astrology to this day. For this episode I decided to interview an expert in Vedic astrology in order to provide western astrologers with a well-rounded introduction to one of the most popular dasha techniques that is used today. Freedom is the author of two books on Indian astrology: Science of Light: An Introduction to Vedic Astrology, and Science of Light, Volume 2: Foundations of Vedic Astrology. He also teaches a course on Vedic astrology, and the next class begins on March 28, 2019. You can find more information on his website: ScienceOfLight.net This episode is meant to be a general introduction to the calculation, conceptualization, and interpretation of the vimshottari dasha system. The outline is largely based on the chapter on dashas in volume 1 of Freedom's book, although the book goes into more detail. There is a long set of show notes below, which outline some of the main points touched on during the course of the episode. This episode is available in both audio and video versions, and you will find links to both at the bottom of this page. Vimshottari Dasha Podcast Outline Here is an outline with some of the major points touched on in this episode: Introduction Introducing Freedom, and talking about his background. Author of Science of Light (2 vols.) Follows the Parashara tradition primarily. Translated Sanskrit excerpts from Parashara in his book. Introduce the concept of dashas and timing (kalana). Understand the past, correctly perceive the present, and predict the future. The birth chart indicates various things. Dashas indicating when the indication will occur during the life. Not all chart placements are activated at all times. Many different dasha systems in Indian astrology. Three broad categories of dasha systems. Different dashas used for different purposes. The most common or popular is the vimshottari dasha system. First appears in Parashara (circa 8th century?). Calculation How to calculate Vimshottari dasha periods, generally speaking. There is a new free online vimshottari dasha calculator on Astro-Seek. Was just launched today to coincide with this episode. Still in development. Report any bugs to the developer. Most programs for Windows like Solar Fire will calculate it; no good ones for Mac. The program Freedom recommends for Windows: http://www.vedicastrologer.org/jh/ Astrodienst has a helpful guide for calculating vimshottari dasha periods, but sadly do not seem to offer chart calculation services for this technique on their site. The technique is calculated roughly as follows: Determine the nakshatra the Moon is located in at birth. The nakshatras are 27 lunar mansions, with 13°20' degrees each. Note that these positions are sidereal. Each nakshatra is associated with a specific planet. Diagram showing the nakshatras and their planetary rulers. Each planet rules a certain number of years: Ketu (south node) is 7 years Venus is 20 years Sun is 6 years Moon is 10 years Mars is 7 years Rahu (north node) is 18 years Jupiter is 16 years Saturn is 19 years Mercury is 17 years Whatever nakshatra the Moon is in, the ruling planet establishes first chapter of life. When that chapter is up, it moves to the ruler of the next nakshatra, in zodiacal order. Note that you must subtract a number of years proportional to how far through the first nakshatra the Moon is from the first period.
