菩薩戒本疏 2.116

2.116

若佛子！護持禁戒，行住坐臥日夜六時讀誦是戒，猶如金剛、如帶持浮囊欲度大海、如草繫比丘，常生大乘善信，自知我是未成之佛、諸佛是已成之佛，發菩提心念念不去心。若起一念二乘外道心者，犯輕垢罪。

"Disciples of the Buddha! Guard and maintain the restrictive precepts; whether walking, standing, sitting, or lying down, during the six periods of the day and night, recite these precepts as if they were adamantine, as if carrying a floating life-preserver wishing to cross a great ocean, or as if you were the monk bound by grass. Constantly generate good faith in the Mahāyāna, knowing of yourself: 'I am a Buddha yet to be accomplished; all Buddhas are Buddhas already accomplished.' Generate the bodhicitta, not departing from it in thought after thought. If one gives rise to a single thought of the two vehicles or non-Buddhists, one commits a duṣkṛta offense."
