大般涅槃經疏 6.6

6.6

From "I now dwell peacefully..." onward is the fourth part, concluding the secret treasury by dwelling peacefully in the three dharmas. This concludes that the three virtues entering the great nirvāṇa constitutes the secret treasury. "Like the worldly letter *i*" concludes the three dots; the text abbreviates and does not conclude with the divine eyes. However, the Buddha constantly dwells peacefully in the three dharmas; that he says "I now" is simply in accord with what is appropriate for the conditions—therefore, saying "for the sake of sentient beings, it is called entering nirvāṇa" is precisely this meaning.
