Kamalaśīla
As regards the argument adduced for proving the existence of Mind,—if the mere fact of certain notions having a cause in general is meant to be proved, then it is superfluous.—This is what is shown in the following—[see verses 631-632 above]
If what is meant to be proved is the eternal and one Mind, then the conclusion is one that is annulled by Inference, and the Reason is ‘Contradictory’. This is what is shown by the words ‘If however, etc. etc.’
‘Destructive of what is desired’;—because what it proves is only the dependence (of the notions cited) upon an impermanent (fleeting) cause which is distinct from the Eye and other organs. Otherwise, if they had an eternal Cause, as the Cause would always be present in its perfect form, the successive appearance of Cognitions would be incongruous.—(631-632)
