यो मामेवमसम्मूढो जानाति पुरुषोत्तमम्। स सर्वविद्भजति मां सर्वभावेन भारत ॥

yo mām evam asammūḍho jānāti puruṣhottamam sa sarva-vid bhajati māṁ sarva-bhāvena bhārata

He who undeluded knoweth Me thus as the Supreme Spirit, he, all-knowing, worshippeth Me with his whole being, O Bhârata.

In plain words: Krishna tells Arjuna that whoever clearly knows him as the Supreme Person knows everything that matters. That person worships him with their whole heart and life.
