Prabhupāda: That is not very good intelligence. You drink the blood of the cow by natural process, which turns into white milk. You'll get better brain, better strength. Therefore cow protection is very essential in Vedic civilization. Therefore we offer respect Kṛṣṇa: "Kṛṣṇa is the benefactor of cows and the brāhmaṇas." Namo brahmaṇya-devāya go-brāhmaṇa-hitāya ca. Go-brāhmaṇa-hitāya ca. Kṛṣṇa is well-wisher first-go, cow. You'll find Kṛṣṇa always with cows. Here is Kṛṣṇa's picture, you see how He's loving the cow and the calf. He's personally teaching from His childhood, from His boyhood. So we should follow. If we want to become Kṛṣṇa conscious, we must give... The calf is also seeing to the face of Kṛṣṇa for protection, and Kṛṣṇa is giving protection, "Yes, I'll give you protection."
So this is the position. And here is also dharma. Religious life must begin very clean. That is also stated in the Bhagavad-gītā,
- yeṣāṁ tv anta-gataṁ pāpaṁ
- janānāṁ puṇya-karmaṇām
- te dvandva-moha-nirmuktā
- bhajante māṁ dṛḍha-vratāḥ
- (BG 7.28)
Sinful life will not... (break) ...that is practical, everyone knows. And we see so many varieties of people, men, in the society, and what is the difference of variety? One has got good brain, another has got dull brain. That is dis... That is the variety. So if you want good brain... Good brain means how to get relief from all the troubles of material existence. That is good brain. And bad brain means to become implicated more and more. They do not know... Because they have got bad brain, they do not know how spirit soul is transmigrating from one body to another, how he is becoming entangled. Today I have got very nice body, American body, but what is the guarantee next life? But they do not believe in the next life because they have no good brain. So in order to understand things as they are, you require good brain, and for good brain, you require milk preparation. In this way, as they've suggested a routine in the śāstra also, and guided by sādhu-guru-śāstra, if we accept, then we shall become very happy in this life and next life also. That is Kṛṣṇa consciousness movement.
