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.
Books are the basis of our movement. Whatever appreaciation we are getting on account of our books, it is because we are following the path chalked out by exalted devotees. We are not writing something whimsical.
To travel in another country, you need visa permission, similarly to go back to Godhead you need permission & mercy from his pure devotee.
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.
