 Tsongkhapa's Golden Garland is his most important early work. It takes the form of a long explanation of the Perfection of Wisdom sūtras, given pride of place in the Kanjur as the foremost words of the Buddha, after the Vinaya section (the codifications of ethical conduct). It is a word-by-word commentary on the topics in the Ornament for the Clear Realizations (Abhisamayālaṃkāra). Tsongkhapa bases his explanation on two sub-commentaries by Ārya Vimuktisena (sixth century?) and Hari Bhadra (end of the eighth century). It propounds a philosophy that later Gelukpas, following the taxonomy developed in the mature works of Tsongkhapa, call Yogācāra-svātantrika-madhyamaka, in essence a Middle Way that incorporates many of the categories of Yogācāra Buddhism, yet does not have the authority of Candrakīrti's Prāsaṅgika interpretation.
