Bhagavad Gita · 9.26

पत्रं पुष्पं फलं तोयं यो मे भक्त्या प्रयच्छति।तदहं भक्त्युपहृतमश्नामि प्रयतात्मनः॥

patraṁ puṣhpaṁ phalaṁ toyaṁ yo me bhaktyā prayachchhati tad ahaṁ bhakty-upahṛtam aśhnāmi prayatātmanaḥ

Whoever offers Me with devotion a leaf, a flower, a fruit, or water — that offering of love, from one of pure heart, I accept.

— Bhagavad Gita 9.26
