O Govinda! Feeling Your separation, I am considering a moment to be like twelve years or more. Tears are flowing from my eyes like torrents of rain, and I am feeling all vacant in the world in your absence.
In the preliminary phase of spiritual life there are diffrent kinds of austerities, penances and similar processes for attaning self-realization. However, even if an executor of these processes is without any material desire, he still cannot achieve devotional service and aspiring by oneself alone to achieve devotional service is also not very hopeful, because Krishna does not agree to award devotional service to merely anyone. Krishna can easily offer a person material happiness or even liberation, but he does not agree very easily to award a person engagement in His devotional service. Devotional service can in fact be attained only through the mercy of a pure devotee.
Krishna Consciousness is not a matter of faith but it is the science of self realization.
First birth is from your parents, but real birth, real life, begins when one accepts a bona fide spiritual master and renders service unto him. Then the path is open for going back to home, back to Godhead, to live eternally in full knowledge and full bliss and in association with the Supreme Personality of Godhead Himself, Lord Krishna. – In his letter to Narayani, 11th June, 1972.
