The research proposal focuses on a small part of the Pramāṇavārttika, one of the main works composed by the Indian philosopher Dharmakīrti (6th-7th cent.). The Pramāṇasiddhi chapter of the Pramāṇavārttika presents something unique in comparison with both previous and later works of the logical-epistemological tradition, that is, a systematic discussion of the four Nobles’ Truths – the central teaching of the Buddha – through the responses to the challenges posed by non-Buddhist and Buddhist thinkers or currents. This allows Dharmakīrti to expound his discourse on liberation and explore a variety of non-Buddhist views on the topic. In this context, he inter alia examines the nature of dīkṣā, ‘initiation’, discussing it in the verses 256-266, which may thus be called “dīkṣā-section”. Work on this section will include a re-edition of the verses of the Pramāṇavārttika together with the related Manorathanandin’s commentary, the Pramāṇavārttikavṛtti, which corresponds to the text at pp. 98,4 to 101,13 in Rāhula Sāṅkṛtyāyana’s edition. A study on the historical-, religious- and philosophical aspects of the texts will accompany the edition.
