SB 7.6.26 — Religion, economic development and sense gratification — these are described in the Vedas as tri-varga, or three ways to salvation. Within these three categories are education and self-realization; ritualistic ceremonies performed according to Vedic injunction; logic; the science of law and order; and the various means of earning one’s livelihood. These are the external subject matters of study in the Vedas, and therefore I consider them material. However, I consider surrender to the lotus feet of Lord Viṣṇu to be transcendental.
SB 7.6.27 — Nārāyaṇa, the Supreme Personality of Godhead, the well-wisher and friend of all living entities, formerly explained this transcendental knowledge to the great saint Nārada. Such knowledge is extremely difficult to understand without the mercy of a saintly person like Nārada, but everyone who has taken shelter of Nārada’s disciplic succession can understand this confidential knowledge.
SB 7.6.28 — Prahlāda Mahārāja continued: I received this knowledge from the great saint Nārada Muni, who is always engaged in devotional service. This knowledge, which is called bhāgavata-dharma, is fully scientific. It is based on logic and philosophy and is free from all material contamination.
