One becomes quickly recognized by the Lord by preaching
If one tries to spread Krsna consciousness all over the world, he should be understood to be performing the best welfare activity. The Lord is automatically very pleased with him. If the Lord is pleased with him, what is left for him to achieve? If one has been recognized by the Lord, even if he does not ask the Lord for anything, the Lord, who is within everyone, supplies him whatever he wants. This is also confirmed in Bhagavad-gita (teaˆ nityabhiyuktanaˆ yoga-kemaˆ vahamy aham [Bg. 9.22]). Again, as stated here, tapyante loka-tapena sadhavah prayao janah. The best welfare activity is raising people to the platform of Krsna consciousness, since the conditioned souls are suffering only for want of Krsna consciousness. The Lord Himself also comes to mitigate the suffering of humanity. All the astras conclude, therefore, that spreading the Krsna consciousness movement is the best welfare activity in the world. Because of the ultimate benefit this bestows upon people in general, the Lord very quickly recognizes such service performed by a devotee.
