Chapters 3 The Bodhisattva's Vow

The Buddha said to Subhūti: "The bodhisattvas and mahāsattvas should subdue their thoughts like this: All the different types of sentient beings, whether they be born from eggs, born from a womb, born from moisture or born spontaneously; whether or not they have form; whether they abide in perceptions or no perceptions; or without either perceptions or non-perceptions, I save them by causing them to enter nirvana without remainder. And when these immeasurable, countless, infinite number of sentient beings have been liberated, in actuality, no sentient being has attained liberation. Why is this so? Subhūti, If a bodhisattva abides in the signs of self, person, sentient being, or life-span, she or he is not a bodhisattva."
