佛遺教經論疏節要 1.395

1.395

汝等但當勤而行之，若於山間、若空澤中、若在樹下、閒處靜室，念所受法勿令忘失，常當自勉精進修之，無為空死後致有悔。

"You must simply practice it diligently, whether in mountain ravines, in empty marshlands, under trees, or in solitary places and quiet rooms. Keep in mind the Dharma you have received, not letting it be forgotten; you must always exert yourselves in vigorous cultivation, and do not die in vain only to have regrets afterward."
