Prabhupada's lecture - Śrīmad-Bhāgavatam 1.8.23 - Los Angeles, April 15, 1973
So Hṛṣīkeśa. Kṛṣṇa is the supreme controller. Hṛṣīka. Hṛṣīka means senses. So we are enjoying our senses, but ultimately the controller is Kṛṣṇa. Suppose this is my hand. I'm claiming it is my hand: "I shall give you a good fist on your..." I'm very much proud. But I am not controller. The controller is Kṛṣṇa. If you, if He withdraws the power of the activity of your arm, you become paralyzed. Although you are claiming, "It is my hand. I shall use it," but when it is paralyzed, you cannot do anything. Therefore I may have possessed this hand by the grace of Kṛṣṇa, but I am not the controller. That is Kṛṣṇa consciousness. Therefore a sane man will think that ultimately if this hand is to be controlled by Kṛṣṇa, then it meant for Kṛṣṇa.
This is the common sense understanding. I am claiming that "This is my hand, this is my leg, this is my ear." Even children says. You ask the children, "What is this?" "It is my hand." But we may claim, but actually it is not our hand. It is given for... Because I wanted to use my hands in so many ways, Kṛṣṇa has given: "All right, you take this hand. Use it." So it is gift of Kṛṣṇa.
