The relative frequency of the quotations from the Upanishads is close to that found in other commentaries of Sankara which are well authenticated.
The citations from non-Upanishadic authority are all found in his other commentaries; the numbers here, though small, show Sankara’s usual reliance on the Gita and the Mokshadharma section of the Mahābharata epic, and the Law-books of Manu and Apastamba. As the basic text is a section of the Apastamba itself, it is natural that there should be here a number of citations of other parts of that book.
