Plenary Portions (BG and SB)
Bhagavad-gita As It Is
BG Chapters 1 - 6
BG 2.12, Purport:
In the Vedas—in the Kaṭha Upaniṣad as well as in the Śvetāśvatara Upaniṣad—it is said that the Supreme Personality of Godhead is the maintainer of innumerable living entities, in terms of their different situations according to individual work and reaction of work. That Supreme Personality of Godhead is also, by His plenary portions, alive in the heart of every living entity. Only saintly persons who can see, within and without, the same Supreme Lord can actually attain to perfect and eternal peace.
