My dear , here is an excerpt from a wonderful letter that Srila Prabhupada wrote from Jaipur, India on 20 January 1972 to his disciple Hansaduta Das:
"Please accept my blessings. I beg to acknowledge receipt of your letter dated January 7, 1972, and with great pleasure I have noted your unbounded enthusiasm to carry out this great mission of spreading the light of love of Godhead in this hellish material world. That is the only requirement for successfully completing the perfection of the living condition, that you should always be enthusiastic to perform services unto the
Lotus Feet of the Lord despite all obstacles, and then you can be assured that all of the other qualities or necessities for pure devotional service will be met, such as patience, determination, etc. and then without doubt you shall be delivered to the realm of unlimited bliss, freed from all anxieties."
So unbounded enthusiasm for preaching and devotional service entitles one to be delivered to the realm of unlimited bliss. The more we endeavor to give Krishna consciousness, the more are blessed with Krishna consciousness. Therefore the most intelligent position is to endeavor as much as possible to make the whole world Krishna conscious.
