治禪病祕要法 2.79

2.79

佛告阿難：「佛滅度後，四部弟子若欲坐禪，先當寂靜端坐七日，然後修心數息七日。復當服此除病等藥，除聲去肶、定心守意、修心修身，調和諸大令不失時。一心一意不犯輕戒及與威儀，於所持戒如護眼目、如重病人隨良醫教。行者亦爾，隨數數增不令退失，如救頭燃，順賢聖語，是名治病服煖身藥。」

The Buddha said to Ānanda: "After the Buddha's parinirvāṇa, if disciples of the four assemblies wish to sit in meditation, they should first sit upright in silence for seven days, and then cultivate the mind through counting the breath for seven days. Furthermore, they should take these sickness-dispelling medicines and the like, dispel sounds and remove numbness, steady the mind and guard intention, cultivate the mind and cultivate the body, and harmonize the elements so as not to miss the proper time. Wholeheartedly and single-mindedly, they must not violate minor precepts or proper deportment; regarding the precepts they uphold, they should protect them as they would their eyes, just as a gravely sick person follows the instructions of a skilled physician. The practitioner should do likewise, following and repeatedly increasing them without letting them decline or be lost, as if extinguishing a fire on one's head, complying with the words of the worthy and holy. This is called curing sickness by taking medicine that warms the body."
