Kamalaśīla was an illustrious scholar who also influenced the development of Tibetan Buddhism by his writings. His most important work, Madhyamakāloka (Light on the Middle Way), presents the Madhyamaka doctrine of emptiness (śūnyatā) and incorporates Tathāgata-Garbha (Essence of Buddhahood) theory perhaps for the first time in the Madhyamaka school; his commentary (Skt., pañjikā) on Śāntarakṣita's Madhyamakālankāra (Ornament of the Middle Way) remains an important assessment of Buddhist philosophy (though a few Geluk scholars doubt its authenticity); his commentary on Śāntarakṣita's Tattvasaṃgraha (Compendium of Reality, tr. G. Jha, 1937–9) contains the first known Buddhist consideration of the Indian Advaita school. In addition to this, Kamalaśīla's three texts on meditation, the Bhavanakrama (Stages on the Meditative Path) represent his own position taken in the debate.
