Bhagavad Gita, Chapter 4, Verse 25

Some Yogis perform sacrifices to Devas alone, while others offer the self as sacrifice by the self in the fire of Brahman alone.

Giving something external is one form of offering. Giving the sense of separate self is a much deeper one.

Both paths named here are real, but they're not treated as equal. Offering objects or effort is a genuine starting point, offering the very idea of 'I' as a separate doer is described as the fuller version of the same gesture.
