Prabhupāda: Yes. So Kṛṣṇa gives that value. Just like Kṛṣṇa gave the value in Bhagavad-gītā, and Arjuna in the beginning denied to fight, but he agreed to fight. He agreed to fight.
Śyāmasundara: Because he was satisfied by his faith in Kṛṣṇa?
Prabhupāda: Yes. This is required.
Śyāmasundara: He says that moral laws are comparable to physical laws. In other words, they are guidelines to elicit certain responses under given conditions. Just like if I throw a ball up, I know it is going to come down. So a moral law will guide me in the same way. If I act in a certain way, there will automatically be a certain result, a response.
Prabhupāda: Yes. Just like we prescribe, ādau śraddhā tato sādhu saṅgasya. If you follow one after another, you get the result. If you have got faith, you make association with devotees. Then the next step, you will be eager to execute devotional service. Ādau śraddhā tataḥ sādhu-sango 'thya bhajana-kriyā 'nartha-nivṛttiḥ syāt (Cc. Madhya 23.14-15). Then all misgivings are eradicated. Then you become firm faith, niṣṭhā, then attachment, one after another. Unless you experience the next result, how can you make progress?
