Dharmakirti

sems kyi rang bzhin 'od gsal te//

dri ma rnams ni glo bur ba//

The nature of mind is clear light,

Defilements are only adventitious.

Commentary on Valid Cognition, chapter II

 

don dam don byed nus pa gang//

de 'dir don dam yod pa yin//

gzhan ni kun rdzob yod pa ste//

That which can ultimately perform a function

Is here said to be ultimately existent.

All else besides has relative existence.

Commentary on Valid Cognition, III, 3
