INTRODUCTION
the date of the copy of the MSS. of VBH. So the upper limit of the date of Jinabhadra is 593 A.D. At any rate one thing is clear that Jinabhadra belongs to the last quarter of the 6th century A.D., which can be pushed further upto 609 A.D. Jinabhadra divides pratyakṣa into mukhya and sāmvyavahārika; the latter being the out-come of the joint operation of senses and mind1. Akalanka also adopts the same method of division of pramana2. Thus Akalanka follows Jinabhadra who himself was an exponent of the Agamic conception of Pramana. The concept of sāmvyahārika pramana, though the word is coined by Buddhist philosophers, is adopted by the Jaina logicians also; Jinabhadra is first to absorb this in Jaina logic.
11. Patrakesari:
According to Anantavirya there was a work of Patrakesari, viz., Trilakṣaṇakadarthana. Tattvasamgraha5 quotes Patrawsāmi's 'anyathanupapannatvam' etc. The inscriptions refer to Pātraswami after Sumati. The three forms of hetu (reason) are propounded by Dignaga and elaborated by Dharmakirti. The oldest reference to Patraswami is made by Santarakṣita (705-762 A.D.) and Karṇakagomi (between the last quarter of 7th and 8th century A.D.). Hence Patraswami must have lived after Dignaga (425 A.D.) and before Santarakṣita. It seems, therefore, that he belongs to the last part of the 6th century A.D. and earlier part of the 7th century A.D.; his famous verse 'anyathanupannatva' is incorporated by Akalanka in his Nyayaviniścaya?.
12. Bhartṛhari:
It is generally accepted on the strength of I-Tsing's record of his travels that Bhartṛhari lived in 650 A.D.; for he refers to Bhartṛhari's death just before forty years from the time of his records (691 A.D.). But recent researches have thrown much light and suggest a drift from the accepted date. Muni Jambuvijayaji in his article on "Jainācārya Mallavadi ane Bhartṛhari no Samaya"s has put forth some arguments to reject the said date. According to him:
1 Viseṣāvasyakabhāṣya, v. 95.
2 Laghiyastraya, v. 3.
3 Pramāṇavārtika, I. 7.
