“So śāstra is like that – bhūta, bhaviṣya, vartamān. Bhūta means “past,” and bhaviṣya means “future,” and vartamān means “present.” Śāstra will give you direction about past, present and future. That is śāstra. That is called scripture. Even there is system of astrology, it is called Bhṛgu-saṁhitā. From that Bhṛgu-saṁhitā, still, if you go to India, there are many scholars expert in Bhṛgu-saṁhitā astrology. They will tell you, if you approach one of them, he will give you the history of your past life, the history of your present life, and the history of your future life. Their astronomical calculation they give you. At least you will understand so many things of your past life. That will be the evidence. And it will be future life also. Bhṛgu-saṁhitā. That Bhṛgu Muni made this scientific knowledge long, long ago. He has left such calculation, those who are expert. It is simply calculation. They will make a check, and from that check the ślokas are there – “This check means…, this calculation means this; this calculation means like this.”
