Prabhupāda: Yes. Devotees, how much they are grateful, kṛṣṇa-prasāda. "Kṛṣṇa, You have sent so nice fruit, nice flower. First of all You enjoy." Oh, God is very satisfied. Just like a boy, "My dear father, this sweetmeat is very nice. You take." Father knows that sweetmeat was purchased by him. Where the boy can get the sweetmeat? But because the son is offering to the father in love and affection, father says: "Oh, you have give me. It is very nice."
Therefore we cannot offer any Kṛṣṇa. Kṛṣṇa is self-sufficient. He does not require your offering of this foodstuff, that food. But if you offer with affection and love He accepts. And as soon as Kṛṣṇa accepts, your life is sanctified immediately. Therefore we should eat kṛṣṇa-prasāda, nothing more. Not in the hotel, not in the restaurant. Simply kṛṣṇa-prasāda. That will keep me purified always.
Go on.
Tamāla Kṛṣṇa: "Others, who prepare food for personal sense enjoyment, verily eat only sin."
Prabhupāda: Yes. Simply you have nice foodstuff, palatable dishes. You can prepare palatable dishes for Kṛṣṇa. There are hundreds and thousands of preparation. But as soon as you prepare for yourself or you try to satisfy your tongue, then you are bound up by the laws of nature. Anything. Because that is sinful. Sinful.
If you do not acknowledge, if you do not acknowledge the authority, if you do not feel your gratitude for the supplier, then you are a thief. Especially it is mentioned, "It is thief." I am taking your things, I am eating, but I am not feeling any gratitude for you, then I am a thief. Yes.
Go on.
Tamāla Kṛṣṇa: Fourteen: "All living bodies subsist on food grains. Food grains are produced from rains. Rains come from performance of sacrifice, and sacrifice is born of man's work."
Prabhupāda: This is a cycle. Cycle. We are living on food grains. We cannot live on meat-eating. It is not possible. However a great meat-eater may be, he must have some grains, some vegetables. That is his life. Yes. Therefore grains, vegetables, they are actually our food. Now, I am living and getting energy by eating grains and vegetables, and how my energy should be utilized?
It should be utilized for the purpose from where I am getting energy. I am getting energy from the Supreme Lord by supply of this foodstuff; therefore my energy should be utilized for the service of the Supreme Lord. That is called sacrifice.
So I should be strong enough to offer sacrifice to the Lord. By sacrifice, the demigods, the Lord will be pleased and there will be sufficient rain. There will be again production. Again you will eat. Again you will get strength. Again you will offer saṅkīrtana. This cycle. This cycle must go on. This cycle.
You get from the Supreme Lord supply by His natural ways. You get strength. And your strength should be utilized not for sense gratification. "Because I am now very stout and strong, oh, let me enjoy senses," then you are sinful. And if you use your strength for satisfying the Supreme Lord, then your energy is properly utilized. This is the way.
