Prabhupāda: Yes, everything necessary as we have prescribed. If you think that it is not necessary, unnecessary, then you under the māyā. Why do you take that, "Is it necessary?" That means you are not strong enough. You cannot follow; therefore you say, "Is it necessary?" You are considering. That means you are becoming prey to māyā. As soon as you ask this, that means you have already fallen a victim of māyā.
Devotee (1): Kṛṣṇa says "without doubting."
Prabhupāda: Yes.
Hari-śauri: So how to get those people who are immersed in māyā to become serious? When we go out and we preach our saṅkīrtana movement, how to get...
Prabhupāda: They will become gradually. Not all of a sudden. They are purchasing one book. They will read, and gradually they will be elevated. You go to school, but all of a sudden, you cannot say that "I am M.A." You have to wait. That is called dhairya, utsāhād dhairyāt. One should be very enthusiastic, at the same time, patient. If you think that "I am very enthusiastic; still, I am not getting the result," be patient. Niścayāt. Be sure the result will come, but be patient. These are the ways. Utsāhād dhairyāt niścayāt tat-tat-karma-pravartanāt. You have to follow the regulative principles. Sato vṛtteḥ. You should be honest. You are not following, and still, you say "I am devotee." That means you are not honest. Sato vṛtteḥ sādhu-saṅge, and in the association of devotees. Ṣaḍbhir bhaktiḥ prasidhyati. By following these six principles, you advance. This is the Rūpa Gosvāmī's instruction.
