Paramahaṁsa: What does it mean when they say that failure is the pillar of success?
Prabhupāda: Yes. For whom? Who is actually searching after success? Not for the fool. Anyone who is trying for attaining success, for him, failure is also success, because he's making progress. Harer nāma harer nāma . . . (CC Adi 17.21). (japa)
God says: "Many ways." That's all right. But why does He says that, "If you want to know Me perfectly, and without any doubt, then this is the process, bhakti"? Other processes are there, but by those processes you cannot understand. Just like practically, call anyone, so-called yogī, so-called jñānīs, they'll not understand Kṛṣṇa. They'll not understand Kṛṣṇa. So all other paths that are recommended, by those paths you cannot understand God perfectly and without any doubt. Therefore God says clearly, bhaktyā mām abhijānāti yāvān yaś cāsmi tattvataḥ (BG 18.55): "Actually what I am, that can be understood by bhakti-yoga." Other system, you'll . . . I explained that last night. That is partial understanding. That is not full understanding.
