Just like your father has given you so many things and you are obliged, "Oh, our father is maintaining us." And if you cook something and give it to the father first, "My dear father, I have cooked this. It is very nice. You first of all . . ." "Oh, it is very nice? All right, give me." The father will be so much pleased: "Oh, here is my dear son." It is father's property. You cannot give anything to the father.
Similarly, you have nothing to offer to Kṛṣṇa. Simply you have to become little intelligent. That's all. Not rascal. If you remain rascal, then your human life is spoiled. If you become little intelligent, then your human life is successful.
This is intelligence that, "God is giving us . . . God is giving us daily bread. Why not offer to God first?" That is intelligence. And simply, "God is giving me bread. I shall eat. That's all . . ." I am meant for eating only? And why not offering? God will not eat?
Simply you feel gratitude: "Oh, God has given me this bread. Let me offer it to God first of all. Then I take." What is the wrong there? What is loss there?
But these narādhama, lowest of the mankind, they even do not recognize this. Lowest of . . . they have been described in Bhagavad . . . narādhama. Na māṁ duṣkṛtina mūḍhāḥ prapadyante narādhamāḥ, māyayāpahṛta-jñānā (BG 7.15). His intelligence, his knowledge, has been taken away by māyā.
He has not this knowledge even that, "God has given me to eat. Why not offer first of all to God?" This intelligence has been taken away by māyā. Therefore they are narādhama. Na māṁ duṣkṛtino mūḍhāḥ prapadyante narādhamāḥ.
So those who are narādhama, lowest of the mankind . . . just like here, something being offered to Kṛṣṇa, to God, He will eat it, but He will leave everything for you as prasādam. How? Pūrṇāt pūrṇam udacyate.
Pūrṇasya pūrṇam ādāya pūrṇam eva avaśiṣyate (ISO Invocation). This is God's power. He will eat everything, but He will keep everything for you as prasādam. Pūrṇasya pūrṇam ādāya. Taking everything, but still, it is there.
So this is the process, how to increase your attachment for Kṛṣṇa. This bhakti-yoga, or Kṛṣṇa consciousness movement, is nothing . . . we do not say that, "You Christian, you are good. I am Hindu, I am bad." Or "You are bad, I am good." We don't say that. We simply say that, "It is your right now, this human form of body, how to love God." That's all. "You have loved so long dog. Now you try to love God."
