To be nonviolent to human beings and to be a killer or enemy of the poor animals is Satan's philosophy. In this age there is always enmity against poor animals, and therefore the poor creatures are always anxious. The reaction of the poor animals is being forced on human society, and therefore there is always strain of cold or hot war between men, individually, collectively or nationally.
A. C. Bhaktivedanta Swami PrabhupadaThe artist draws a picture of a rose very nicely with all attention and artistic sense, and yet it does not become as perfect as the real rose. If that is the real fact, how can we say that the real rose has taken its shape without Intelligence behind the beauty?
A. C. Bhaktivedanta Swami PrabhupadaReligion without philosophy is sentiment, or sometimes fanaticism, while philosophy without religion is mental speculation.
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.
