For so many countless lifetimes the conditioned souls have been giving all of their service and energy to the service of Maya, and I am requesting all of my disciples that for this one lifetime you give all of your energy and service to Krishna. The spiritual force is eternal, so to give simply one lifetime to Krishna is not a very difficult thing. And yet if we are serious in executing the devotional principles, this one lifetime of service to Krishna will absolute and final solution to all the problems of life.
Letter to Madhudvisa, 7 September, 1969
