[Treatise:] and make great vows, [wishing to liberate all realms of sentient beings down to the end of the future, without limiting the number of kalpas, for they take all sentient beings as their own self, yet do not grasp at the characteristic of sentient beings.] [Commentary:] This is establishing vows on the basis of the compassionate mind. "Wishing to... down to..." and so forth is the vast vow. "Without limiting..." and so forth is the vow of long duration. The first also contains the supreme vow, because speaking of "liberating" is the supreme aspiration.
