Spiritual activities other than bhakti-yoga are divided into three categories-speculative activity conducted by the jñāna-sampradāya (learned scholars), fruitive activity conducted by the general populace according to Vedic regulations, and the activities of transcendentalists not engaged in devotional service. There are many different branches of these categories, but the Supreme Personality of Godhead, by His inconceivable potencies and transcendental qualities, attracts the mind of the student engaged in the activities of karma, jñāna, yoga, and so forth. The Supreme Lord is full of inconceivable potencies, which are related to His person, His energies and His transcendental qualities. All of these are very attractive to the serious student. Consequently the Lord is known as Kṛṣṇa, the all-attractive one.
