You are trying to spread Krsna consciousness with so much endeavor. It’s not that cent per cent people of the world will take. That is not possible. Ei rupe brahmanda bhramite kono bhagyavan jiva [Cc. Madhya 19.151]. Only the fortunate persons will be able to take it. So we should not be disappointed that “Nobody, majority of people, do not take this. What is the use of? Let me sit down in Vrndavana and chant Hare Krsna mantra.” No. Caitanya Mahaprabhu, He also did it. He never sat down tightly in Vrndavana. He also did it. He traveled all over the India and took so much trouble. So preaching is very important, and you should engage. That will help you. Every one of you should be pure in your activities and try to preach Krsna consciousness as far as possible. If you remain pure, then your preaching will be successful and you’ll get encouragement. That is the instruction of all Vaisnavas.
From Srila Prabhupada’s lecture on Srimad-Bhagavatam 7.6.7 — December 9, 1975, Vrndavana
