“Expound me unto the Brāhmaṇa who guards his treasures and is never careless,—and whom thou knowest to be pure, self-controlled and a duly qualified student.”—(115)

Medhātithi’s commentary (manubhāṣya):
That pupil whom thou knowest to be ‘pure’ ‘self-controlled’—i.e.,having full control over his senses; and a ‘qualified student,’ ever attentive ;—‘unto him expound me.’ He who guards his treasures, being never careless; he never commits mistakes, never fails, being ever attentive to his business.

What is deduced from this valedictory description is the advice that learning should be imparted to the pupils already described above as qualified (under 109), only when they fulfil the conditions described in the present verse.—(115)
