One should endeavor for that which is never obtained by wandering up and down the universe as a result of the reactions of karma. What is that? One should endeavor to become Krsna conscious. 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 (tesam nityabhiyuktanam yoga-ksemam vahamy aham [Bg. 9.22]). Again, as stated here, tapyante loka-tapena sadhavah prayaso 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.

Whenever and wherever there is a decline in religious practice, O descendant of Bharata, and a predominant rise of irreligionat that time I descend Myself. To deliver the pious and to annihilate the miscreants, as well as to reestablish the principles of religion, I advent Myself millennium after millennium. (Bg. 4.78) All the sastras 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.
