  In addition to Tattvasaṃgraha, Śāntarakṣita wrote commentaries on Dharmakīrti’s Vādanyāya (Methods of debate) and Jñānagarbha’s Satyadvayavibhaṅga. His most original contribution to the development of Madhyamaka philosophy is a verse treatise called Madhyamakālaṃkāra (Ornament of Centrism), which contains ninety-seven stanzas, to which he also provided a prose commentary.
