 Kamalaśīla’s definition of conventional truth stresses epistemic error (brānta jñāna / rnam shes khrul ba) in as much as he does stress on non-erroneous epistemic perspective (abrānta jñāna / rnam shes ma khrul ba) in his definition of the ultimate truth. So on his definition, the nature of all entities, illusory persons and the like, is classified into two truths by virtue of erroneous (brānta / khrula ba) and non-erroneous cognition through which they are each represented.
