Medhātithi’s commentary (manubhāṣya):
This verse introduces what is going to be described below. ‘Ten-fold’—That which has ten ‘folds’ or forms.

‘Be observed’—Always be performed.

Though all these have already been mentioned before, yet they are repeated here in order to indicate their great importance; and this repetition also lends support to the view that it is the combination of ‘Knowledge’ and ‘Action’ that accomplishes the hightest end of man—(91)
