Dhammapada · 18.15

Dadāti ve yathāsaddhaṃ, yathāpasādanaṃ jano;Tattha yo maṅku bhavati, paresaṃ pānabhojane;Na so divā vā rattiṃ vā, samādhiṃ adhigacchati.

Dadati ve yathasaddham, yathapasadanam jano; Tattha yo manku bhavati, paresam panabhojane; Na so diva va rattim va, samadhim adhigacchati.

People give according to their faith and confidence. Whoever becomes displeased with others' food and drink — he by day or night does not attain concentration.
