There are many examples in history of persons who have been very much disabled physically, but still have executed Krishna Consciousness. Still, up to date in places like Vrndavana, India, there are many persons who are blind, crippled, lame, deformed, etc., but they are determined to practice Krishna Consciousness to their best ability. So, you should also do like that. Simply be determined to practice the process of Bhakti-yoga with whatever abilities you may have. If you are really sincere, then Krishna will give you help.

As long as the body will be there, there will only be pain. Pleasure is only a misconception. Do not be sorry if you are in an "unfortunate'' situation. It can also be fortunate if you take advantage by becoming serious to become Krsna consciousness. Follow the regulative principles, chant 16 rounds and as far as possible render service and study my books. Success is sure.
