 There could hardly be a better source of information on the true affiliation of Jayarāśi than the author himself. He nowhere states in his work that he is a Cārvāka / Lokāyata, in which he does not differ from all other Indian authors who nowhere mention their philosophical affiliations in the form: ‘The author of the present work is Buddhist’ or ‘I am a follower of the Nyāya school’. In most cases, such affiliations are communicated through the opening sections, e.g. in the introductory verses (maṅgalâcaraṇa), or in the colophons, but usually an indirect manner, e.g. by paying homage to the Awakened One (buddha) or to a guru or Mahêśvara, or through some other hint, but it is hardly ever done directly, in an unequivocal manner. Unfortunately, the preserved text of Tattvôpaplava-siṁha does not contain any introductory verses (probably there were none). The only concealed information in the opening section of the work could be found the first verse that occurs in the very beginning which says: ‘The worldly path (laukiko mārgaḥ) should be followed…/ With respect to everyday practice of the world (loka-vyavahāra), the fool and the wise are similar’ (TUS, p.1.9–10 = Franco (1987: 68–6–7)  = Solomon (2010: 1–2) = Jha (2013: 2)), quoted from some other source, taken as authoritative by Jayarāśi. The expression ‘the worldly path’ (laukiko mārgaḥ) often occurs as a reference to the Lokāyata (‘the followers of the worldly [practice]’), e.g. by Haribhadra in his ŚVS1.64. Most importantly, however, Jayarāśi on several occasions quotes verses of Bṛhaspati in order to either support his own opinion or to show that there is no disagreement between the Tattvôpaplava-siṁha and the tradition of Bṛhaspati  (cf. Franco (1987: 5)). Further, he explicitly mentions the materialist teacher by name and refers to him with reverence ‘Honourable Bṛhaspati’ (bhagavān bṛhaspatiḥ, TUS, p.45.10–11 = Franco (1987: 228.10)  = Solomon (2010: 229) = Jha (2013:  187)),[1]  the reverential term occurring only once in the whole work. This is rather unique, for Jayarāśi does not seem to follow any authorities or to quote passages and opinions which he unreservedly views in favourable light. There can hardly be any doubt, that Jayarāśi placed himself within that tradition and apparently acknowledged that he was originally trained within it.
