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)
