He who, undeluded, knows Me thus as the highest Purusha, he, knowing all, worships Me with his whole being (heart), O Arjuna.

Whoever, free of delusion, knows me thus as the Supreme Person knows all, and worships me with his whole being, Bharata.

Knowing Krishna as the Supreme Person is called knowledge of everything, because it grasps the root of all that exists. Such a knower is not merely informed but responds with his whole being in worship, bhajati. The verse joins knowledge (jñāna) and devotion (bhakti) instead of setting them against each other. One who truly understands does not stop at understanding; the insight becomes love and turning of the whole person toward the source.
