Question: How can you use something in Kṛṣṇa's service? What is the process to use things in Kṛṣṇa's service?
Prabhupāda: Kṛṣṇa's service, as we know what is meant by service: you carry the order of some person. That is service. Master orders, and the servant carries out the order. This is service. Just like in the Bhagavad-gītā the master, Kṛṣṇa, orders Arjuna to fight. He was not willing to fight for his personal interest, but when Kṛṣṇa ordered him that, "You must fight," he fought. That is service. We should dedicate our lives to Kṛṣṇa, and whatever He says, we carry out. That is service.
