Kamalaśīla
It has been argued, under Text 3178, that—“the beginninglessness that is asserted in regard to the composer and the utterances emanating from him is itself based upon two invalid notions, etc. etc.”.
The answer to this is as follows:—[see verses 3478-3479 above]
When we assert Beginninglessness, it is not as a reason for reliability;.because such a reason, as present in the absence of the Probandum also, would be ‘Inconclusive’, Hence, the objection that you have urged has been urged by imputing to us a view that is not held by us.—(3478-3479)
