Karma, you have to work. You cannot maintain yourself without working. That is material world. Material world is not spiritual world. In the spiritual world you haven't got to work, neither you have to eat. Everything is complete. But in the material world means for your maintenance you have to work. But that work is very simple. Grow some food grains and keep some cows, take the milk, and just prepare nice foodstuff and eat. Patraṁ puṣpaṁ phalaṁ toyam (BG 9.26). Keep Kṛṣṇa, the Supreme Personality of Godhead, Deity, at home, and Kṛṣṇa is pleased even you simply offer little fruit and little flower.
So Kṛṣṇa doesn't want anything else. Kṛṣṇa does not say, "Give Me meat. Give Me eggs. Give Me fish." No. He says, patraṁ puṣpaṁ phalaṁ toyaṁ yo me bhaktyā prayacchati. So if you are devotee, you cannot take anything which is not offered to Kṛṣṇa. So Kṛṣṇa. . . I should offer to Kṛṣṇa what He wants. Just like if you want to offer me something, so you inquire that "What shall I offer you? What do you like?" So similarly, if you invite Kṛṣṇa to live in your house or temple, then you should ask Kṛṣṇa, "Sir, what can I offer You?" The Kṛṣṇa said, patraṁ puṣpaṁ phalaṁ toyaṁ yo me bhaktyā prayacchati (BG 9.26). Kṛṣṇa said that "You give Me patram, means vegetables, flowers, fruits, and phalam, fruits, and some liquid, water or milk." Kṛṣṇa does not say, "You give Me meat or egg or fish." No. Kṛṣṇa can eat everything, He's all-powerful, but He does not eat.
