Translator: He is saying that actually there is no difference between, for example, chanting the words "tree, tree, tree" again and again or the chanting of Hare Kṛṣṇa. It depends on the meaning that you put into the word, and if you chant a particular word like Hare Kṛṣṇa and you have a particular meaning, like a, for this particular word, then it might be something like auto-suggestion to you.
Prabhupāda: I have already explained that God and His name, the one, Absolute. In the material world, your name and you person, they are two different things. That is difference between God and you. So therefore, by chanting God's name, you actually contact with God. But in the material world that is not possible. Suppose I am thirsty, I want water. If I chant "water, water," it will not act. But in the case of chanting the holy name of God, it is as good as to associate with God. Try to understand.
