Bhagavad Gita
Chapter 9 · Verse 26
पत्रं पुष्पं फलं तोयं यो मे भक्त्या प्रयच्छति। तदहं भक्त्युपहृतमश्नामि प्रयतात्मनः॥
patraṁ puṣpaṁ phalaṁ toyaṁ yo me bhaktyā prayacchati, tad ahaṁ bhakty-upahṛtam aśnāmi prayatātmanaḥ
It's the sincerity of an offering, not its size, that gives it worth. A small gesture given wholeheartedly outweighs a grand one given carelessly.
A small gift given with a whole heart is never small.
