佛遺教經論疏節要 1.149

1.149

汝等比丘！晝則勤心修習善法無令失時，初夜後夜亦勿有廢，中夜誦經以自消息。無以睡眠因緣，令一生空過，無所得也。

"You bhikṣus! During the day, with diligent minds cultivate and practice wholesome dharmas, not letting the time be lost. In the early night and late night, do not abandon them either. In the middle of the night, recite the sūtras to regulate yourselves. Do not, on account of sleep, let an entire lifetime pass in vain with nothing attained."
