of a cognition is not dependent on excellence. But if correctness is from its own cause alone, and incorrectness from a defect, then it makes sense that cognitions such as mother-of-pearl as silver, through their own cause and through a defect, refer to what is real, such as whiteness, and what is unreal, such as silverness. Therefore it is established: validity is established intrinsically for all cognitions, and that [validity] is unsublated in the case of the Veda.
This Determination of Intrinsic Validity has been composed by Pārthasārathi Miśra
to dispel the delusion arising from disputes among commentaries.
