“People are being a human being, we should be concerned not to neglect this opportunity we have to fully develop our consciousness.
Why someone would take animal birth? Of course one thing would be thinking about the animal at the end of life. Other thing is to develop a consciousness which is more suited to the next birth being an animal birth, than a human being.
Like say somebody is drunk all the time, or something, that’s just always in a stooper. They’re not, they don’t want to be very conscious of whats going on. Human being is much more aware of the realities than an animal. Animal’s consciousness is you know, blocked into a limited sphere of understanding. So they would prefer to not have to deal with the problems of life. That’s why they are remaining intoxicated.
So at time of death, they may get such a birth, that they can just, you know… ignorance is bliss, or…. They don’t have to deal with it, and just deal with the priorities of life like eating, sleeping, mating and defending.
But that’s a big waste. As a human being, we’ve have already gone through 8 Million 400 Thousand species of life of transmigration, a kind of spiritual evolution of consciousness. And being a human being, we should actually perfect our human life by fully developing our potential.“HH Jayapataka Swami Lecture: BG 8.6
