Prabhupāda: If Kṛṣṇa says that, "You give me meat," then we can offer Kṛṣṇa meat also. But Kṛṣṇa does not say that. Kṛṣṇa says, "Give Me fruits, flowers, grains." So we have no quarrel with the meat-eaters. Let them do whatever he likes. But our concern is that unless Kṛṣṇa takes, we don't take.
So in order to become Kṛṣṇa conscious, this is necessary, just like an important segment of the work. We cannot accept anything which is not offered to Kṛṣṇa. Therefore this diet, this sort of diet, as you have tasted in our Love Feast, that is important. We cannot take outside the scope. So in that sense, diet is important. Besides that, from health point of view also you require a balanced food—carbohydrate, starch, protein and fat. That is scientific. So fat we are getting from milk, butter.
So if I can get fat from milk and butter, why shall I kill the cow and animal? This is humanity. My necessity is to get some milk and fat. The cow is supplying you milk and fat sufficiently. Why should you kill it? I am going to be Kṛṣṇa conscious, God conscious, and I am killing another God's creature? So it is very important work to select diet, if anyone is serious to become God conscious, or Kṛṣṇa conscious. Therefore in our program meat-eating is forbidden. So diet is very important in that sense.
The next question is, "So, what is the significance . . ." I think I've already explained this. "Is there a probationary period for Kṛṣṇa consciousness, or does one attain this enlightening according to his own rate of development?" Yes. Everything requires little enthusiasm. Just like a boy is going to school with no enthusiasm and a boy is going to school with nice enthusiasm. One boy is passing in the first class, first division, and another boy is failing or he's passing in the third division. So the probation period, of course, I've already explained: to associate with us, the second stage. First stage is faith and respect, the second stage is association. That is probational period.
And so far attaining enlightenment according to one's rate of development, that development depends on your enthusiasm, how far you are serious. But one should become very serious. That is the law in every sphere of achievement. So for attaining to the perfectional stage of Kṛṣṇa consciousness, one should be very much enthusiastic. Yes. I must attain to the perfectional stage in this life.
And then one should be patient also. Enthusiasm does not mean if I attain something, immediately the result is immediate. No. The result may be delayed, but we should not be disturbed. But we must go on working with enthusiasm. This is called patience. So enthusiasm, patience and confidence. Because we believe in Kṛṣṇa. Kṛṣṇa says that if you do this, you get this result.
Therefore I must have confidence. Just like Kṛṣṇa says that simply by understanding Him, what He is, how does He come, how does He walk, one immediately gets passport to enter into the spiritual kingdom. So we must have confidence that, "I am working in Kṛṣṇa consciousness, I must go back to Godhead, back to home." This confidence. So enthusiasm, patience, confidence.
And . . . uttsayād dhairyāt tat-tat-karma . . . niścayād dhairyāt tat-tat-karma-pravartanā (Upadeśāmṛta 3). Simply enthusiasm but no work . . . but you must be engaged in the prescribed duties of Kṛṣṇa consciousness. And you must keep always yourself in the association of devotees. These things are, I mean to say, impetus for development of Kṛṣṇa consciousness. So the more you enthuse yourself with these six principles: patience, enthusiasm, then confidence, then engaging in the activities, keeping association with devotees and avoiding association with nondevotees . . . that is also another thing. Just like if you want to ignite a fire, then the more the dried the wood is, you get good fire. If you get wet wood, the fire is very difficult to burn.Therefore we should keep ourself dry from being wet by the association of nondevotees.
