Bhagavad Gita, Chapter 9, Verse 26

Whoever with devotion offers Me a leaf, a flower, a fruit, or water, that I accept, the devout gift of the pure-minded.

An offering doesn't need to be large. It needs to be given with feeling.

Naming something as small as a leaf or a little water as fully enough makes a direct point about what matters in the exchange. Size and feeling are shown as entirely separate measures.
