The Bharatiya Vidya Bhavan Institute of Astrology in Delhi is the best among the schools that offer astrology courses and undertake research on the topic. Legendary astrologer Shri K.N. Rao founded this institute’s current astrology programme in 1987. When this institute celebrated its silver jubilee (25 years) in 2013, more than 20,000 students had finished its astrology course. You may learn more about their astrology courses by visiting their website, which is listed below.
Aside from that, the Bharatiya Vidya Bhavan Education Trust in Mumbai and Bangalore offers astrological studies. The following links will take you to their individual websites where you can learn more about the subject.
If you live outside of Delhi-NCR, Mumbai, or Bangalore, you can learn astrology at ICAS (Indian Council of Astrological Sciences) facilities. Dr. B.V. Rama, the late founder of this prestigious institute, established it in November 1984 with the goal of establishing an All India Body for the organized propagation of astrology. ICAS currently has over 40 facilities across India that offer courses on the subject. You can learn more about it by visiting their website, which is shown below.
However, these institutes are limited by the fact that they are not accredited by any federal or state government-run university. So, while these private institutes will provide you with the best knowledge and faculty to learn astrology, you will not receive any credential or degree that is recognized by any university. So, if you want to earn a degree in astrology, you’ll have no alternative except to enroll in a UGC-accredited university that offers astrology courses.
