The symptoms of birth, one can understand, of course, through abhijñā, those who are abhijñā. And the word is used guṇabhijñā jñāpakaḥ. Guṇābhijñā, guṇābhijñāpako yathā. By the guṇas, one can—guṇa means quality—one can understand the past and future. Still in India there is an astrological system, it is called Bhṛgu-saṁhitā. That Bhṛgu-saṁ . . . according to that Bhṛgu-saṁhitā, the astrologer can say what the man was in the past and what he's going to be in future. And present also.
So, generally we can understand from the śāstra that according to guṇa—sattva-guṇa, rajo-guṇa, tamo-guṇa—those who are in sattva-guṇa, they are going higher planetary system; rajo-guṇa, in the same platform; tamo-guṇa, going down. So the human endeavor should be how to increase the sattva-guṇa quality of the man. That is the duty of all guardians. State, king, government—everyone should. If you do not make such attempt to elevate your dependent towards the sattva-guṇa platform, simply lamenting, what will do good to you? "Our position is this. Now it is uncontrollable, the things are going bad, there are problems." Yes, problem must be there, because the aim of life should be known. They do not know. The modern civilization, they do not know what is the aim of life, how life is going on, eternally, how it is implicated, how to entangle. So many things are there; it is a great science.
So the Kṛṣṇa consciousness movement is trying to establish this science. Our real mission is how the human society will be happy. That is the duty of all saintly person.
