SB 5.12.12 — My dear King Rahūgaṇa, unless one has the opportunity to smear his entire body with the dust of the lotus feet of great devotees, one cannot realize the Absolute Truth. One cannot realize the Absolute Truth simply by observing celibacy [brahmacarya], strictly following the rules and regulations of householder life, leaving home as a vānaprastha, accepting sannyāsa, or undergoing severe penances in winter by keeping oneself submerged in water or surrounding oneself in summer by fire and the scorching heat of the sun. There are many other processes to understand the Absolute Truth, but the Absolute Truth is only revealed to one who has attained the mercy of a great devotee.
SB 5.12.13 — Who are the pure devotees mentioned here? In an assembly of pure devotees, there is no question of discussing material subjects like politics and sociology. In an assembly of pure devotees, there is discussion only of the qualities, forms and pastimes of the Supreme Personality of Godhead. He is praised and worshiped with full attention. In the association of pure devotees, by constantly hearing such topics respectfully, even a person who wants to merge into the existence of the Absolute Truth abandons this idea and gradually becomes attached to the service of Vāsudeva.
