Therefore when the soul goes away, these rascals says, "heart failure." Not heart failure, the soul has gone from the heart. Heart is also mechanical thing, but the sitting place of the soul is there. So heart failure means the soul has gone from the heart. Sarvasya cāhaṁ hṛdi—hṛdi means heart. The location also being specified—here is soul and Supersoul. Find out, if you have got such scientific method. But they cannot find it out. Therefore, the rascals say there is no God, there is no soul, simply this lump of matter, that's all.
So anyone who thinks like that, he's described as go-khara. Go-khara means, go means cows and khara means asses. Those who are identifying with this body as the self... Yasyātmā buddhi-kunape tri-dhātuke. Kunape. This body is a bag of bones and flesh with urine and stool and blood and so many other things. But if you are scientist, advanced, then I can supply you immense bones, immense blood, immense urine, immense stool, manufacture one body if you are scientist. I give you ingredients. Immense, any quantity. But you just manufacture one ant. And still you are thinking that "science, science." You cannot do anything.
