This is the Tengyur’s section of commentaries on the Perfection of Wisdom (ཤེས་ཕྱིན་, shes phyin, prajñāpāramitā), containing thirty-eight works (D.3813-D.3850) in sixteen volumes. Zhuchen’s catalog arranges these, first, according to their association with four key texts (or groups of texts) related to the Perfection of Wisdom:
On the whole, the famous Ornament for Clear Realization dominates the overall Perfection of Wisdom section. The Ornament itself begins the section, and the next twenty works are related to it. Some works comment upon the Ornament itself, while some use it as a framework for interpreting the Perfection of Wisdom scriptures.
Following the “four chariots” section, Zhuchen places thirteen more Perfection of Wisdom treatises (D.3838-D.3850) in a “miscellaneous” category that concludes the section.
