假使一月，常以衣食，

供养恭敬，一切众生，

不如有人，一念念佛，

所得功德，十六分一。

– 释迦牟尼佛

《大般涅槃经》

If for one month, constantly with clothing and food, offering reverently, to all sentient beings, this is not equal to having a person, with one thought mindful of Buddha, with those attained meritorious virtues, being sixteen parts’ one [i.e. one-sixteenth: 1/16].

– Śākyamuni Buddha

(Mahāparinirvāṇa Sūtra)
