Devotee: "Even if Arjuna did not believe in the existence of the soul, as in the vaibhāṣika philosophy, there would still have been no cause for lamentation. Nobody would lament the loss of a certain bulk of chemicals and stop discharging his prescribed duties (BG 2.26)."
Prabhupāda: Yes. Suppose some chemical combined bottle is there; by accident it is broken. Does it mean that I shall give up all my duties to be done? And lament for the bottle only? What is this? (laughs) "Arjuna, you are My friend," he was friend of Kṛṣṇa. "You have become so fool that you are lamenting for loss of a chemical bottle?" This is the argument. Yes.
