Explanation
This closes Krishna's chapter on his manifestations (vibhūti). Having listed many of them, he tells Arjuna that a long catalogue is not needed: the whole universe rests on just one portion (aṁśa) of him. Traditions differ on emphasis: Advaita readings stress his transcendence beyond the world, while devotional schools stress his personal, all-sustaining lordship, but all take the verse as pointing to his vastness.
