A grain of devotion is more valuable thank tons of faithlessness.
A. C. Bhaktivedanta Swami PrabhupadaOut of many millions of wandering living entities, one who is very fortunate gets an opportunity to associate with a bonafide spiritual master by the grace of Krishna. By the mercy of both Krishna and the spiritual masters, such a person receives the seed of the creeper of devotional service.
A. C. Bhaktivedanta Swami PrabhupadaIf after accepting the spiritual master and being initiated one does not follow the rules and regulations of devotional service, then he is again fallen.
A. C. Bhaktivedanta Swami PrabhupadaThere is a word Kristos in the Greek dictionary, and this word is supposed to be borrowed from the Sanskrit word "Krishna," and Christ is derived from Kristos.
A. C. Bhaktivedanta Swami PrabhupadaOne must execute devotional service under the guidance of a devotee or directly under the guidance of the Supreme Personality of Godhead. It is not possible, however, to train oneself without guidance from the spiritual master.
A. C. Bhaktivedanta Swami PrabhupadaThe spiritual master and Krishna are two parallel lines. The train, on two tracks, moves forward. The spiritual Master and Krishna are like these two tracks. They must be served simultaneously. Krishna helps one to find bona fide Spiritual Master and bona fide Spiritual Master helps one to understand Krishna. If one does not get bona fide Spiritual Master, then how he can ever understand Krishna ? You cannot serve Krishna without Spiritual Master, or serve just Spiritual Master without serving Krishna. They must be served simultaneously.
