What the Upaniṣads describe as the impersonal Brahman is but the effulgence of His body, and the Lord known as the Supersoul is but His localized plenary portion. He is the Supreme Personality of Godhead, Kṛṣṇa Himself, full with six opulences. He is the Absolute Truth, and no other truth is greater than or equal to Him.
The impersonal Brahman is the goal of those who cultivate the study of books of transcendental knowledge, and the Supersoul is the goal of those who perform the yoga practices. One who knows the Supreme Personality of Godhead surpasses realization of both Brahman and Paramātmā because Bhagavān is the ultimate platform of absolute knowledge.
