 Statements that require interpretation Tsongkhapa groups into those of different Buddhist philosophical schools: in ascending order, Listener (Sk. Śrāvaka) schools based on older Buddhist sources (the Vaibhāṣika and Sautrāntika), Yogācāra schools following Asaṅga and Dignāga/Dharmakīrti, and non-Prāsaṅgika Madhyamaka schools following Bhāviveka and Śāntarakṣita. The Prāsaṅgika-madhyamaka school of Candrakīrti alone captures the final intention of the Buddha. Tsongkhapa was certainly not the first doxographer, but his clear and definitive categories had immense influence on later writers, so much so they have anachronistically been read back into works that were written before his time.
