Thus, through the power of the four contemplative cultivations, upon the cessation of all latent impressions, supreme nirvāṇa in the form of the void will be attained, so that we have accomplished our aim and have nothing to be instructed about. As for the disciples, two things are to be done: yoga and ācāra. There, inquiry for the attainment of an unobtained principle is yoga; accepting the principle stated by the teacher is ācāra. Because they accept what was stated by the teacher, they are the highest, and because they do not make an objection, they are the lowest; hence they are renowned as "Mādhyamikas" (the middle ones).
