Books are the basis; purity is the force; preaching is the essence; utility is the principle.
A. C. Bhaktivedanta Swami PrabhupadaJust try to learn the truth by approaching a spiritual master. Inquire from him submissively and render service unto him. The self-realized soul can impart knowledge unto you because he has seen the truth.
A. C. Bhaktivedanta Swami PrabhupadaTo 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 Lord has different names according to His different activities. For example, His name is Madhusรผdana because He killed the demon of the name Madhu; His name is Govinda because He gives pleasure to the cows and to the senses
