(Thogs med) which is denied by Bu ston on two grounds: that in the tenth chapter it refers to a Tibetan treatise, namely the bka' yan dag pa'i tshad ma, and that the (Abhidharma-)Samuccaya of Asanga35 and the Pramānaviniscaya of the much later Dharmakirti are quoted in it. Bu ston rather thinks that the commentary was composed by a great Tibetan scholar (bod kyi mkhas pa chen po śig gis byas pa) and that it may well have been composed by Klu'i rgyal mtshan. And in his Tanjur catalogue he actually proposes to identify it with the commentary by Klu'i rgyal mtshan in 40 bam po as listed in the catalogue of lHan kar or 'Phan than (sńon gyi dkar chag).36
Bu ston's identification of the commentary that he calls 'grel pa chen po 40 bam po (ChK II 55,7f.) or 'grel chen (TK[Bu) 633,6) with Klu'i rgyal mtshan's commentary in 40 bam po called rgya cher 'grel pa in the lHan kar catalogue (LALOU 531) and the 'Phan than catalogue (NISHIOKA 2920) seems to be based on the identity of size. And this very size of "40 bam po" as indicated in the old catalogues can also serve as a reason for identifying our Vyākhyāna with this work of Klu'i rgyal mtshan.

** SNSūV 159a1f. 35 NISHIOKA thinks that Kun las btus may be Dignāga's Pramānasamuccaya
(Tshad ma'i mdo kun las btus, NISHIOKA 996), evidently because a text of Dharmakirti is also referred to, but would the argument not be much more convincing if it meant in connection with Dharmakirti's work the Abhidharmasamuccaya (mNon pa kun las btus pa in NISHIOKA 708 and Chos mron pa kun las btus pa in

For in the chapter on the evidence that consists in a proof by means of possible (valid cognitions) ('thad pa sgrub pa'i gtan tshigs kyi skabs) of this (commentary) there occurs a reference to a treatise composed by a Tibetan (author) (when it is said): '... are to be seen in the bka' yan dag pa'i tshad ma composed by the divine king Byan chub rdzu 'phrul.' I think that (this commentary) is that (work) which is found in the early catalogue as 'the mDo sde dgons 'grel gyi 'grel pa in 40 bam po composed by the lotsāva Klu'i rgyal mtshan'.")
This information is repeated by the sGra tshad pa in TK(sGra) 564,2-3. Klu'i rgyal mtshan's text is LALOU 531 in the catalogue of lHan kar, and NISHIOKA 2920 in the catalogue of 'Phan than.
