Prabhupāda: Faith means that you are meant for giving some service to Kṛṣṇa. You should stick to that service, that path, in spite of all impediments. That is the passing of test. Just like we are meant for preaching Kṛṣṇa consciousness. So there may be severe test, but still we shall remain determined. That is wanted. There may be so many impediments, punishment; still you should do that. That is wanted. That is test. Not that as soon as there is some difficulty I give it up. There may be severe test, but still we shall not give it up. We must go on. That is determination.
Devotee: Passing the test means executing the order of the spiritual master.
Prabhupāda: Yes, that is spiritual life. One has to take order from the spiritual master and execute it, despite all impediments. That is determination.
