"How one can understand past, present, future? Through the sastra ...There are still astrological calculations in India called Brighu-samhita. If you consult Brighu-samhita, immediately they will give you your past, present and future. Immediately they will give. The astrology science is so perfect. What you were in the past life, what you are at the present and what you are going to be. These three things can be known."

[Srila Prabhupada, Srimad Bhagavatam class, Dallas, July 29, 1975]
