Who, free of foolishness, knows but Me as the supreme person,
They, all-knowing, worship Me with their whole being, O scion of Bharat.
Source: Milind S. Pandit
The wise one, who truly knows Me as the Purushottama, knows everything and worships (or surrenders unto) Me wholeheartedly, O Arjuna. (See also 7.14, 14.26, and 18.66)
Whoever knows Me as the Supreme Personality of Godhead, without doubting, is to be understood as the knower of everything, and He therefore engages himself in full devotional service, O son of Bharata.
