śaṃkaraṃ śaṃkarācāryaṃ keśavaṃ bādarāyaṇam

Śrī Sankara presents the very method of teaching in his commentary. Even though there is no discussion exclusively dealing with the method of teaching in his bhāṣya, Sankara employs the method. We learn how to present a subject-matter, how to expand it and how a word is to be unfolded, how do we come to know exactly what the śruti says in a given sentence-it is for all this that you require a sampradaya. Śrī Sankara says that a teacher should be a sampradaya-vit, a knower of the teaching tradition. He says, asampradayavid mürkhavad upekṣaniyah, just as one keeps away from a murkha, an uninformed person who seriously debates, one has to keep away from asampradayavit.
