Pramana (Sanskrit: प्रमाण, Pramāṇa) literally means "proof" and "means of knowledge".[1][2] In Indian philosophies, pramana are the means which can lead to knowledge, and serve as one of the core concepts in Indian epistemology. It has been one of the key, much debated fields of study in Hinduism, Buddhism and Jainism since ancient times. It is a theory of knowledge, and encompasses one or more reliable and valid means by which human beings gain accurate, true knowledge.[2] The focus of pramana is how correct knowledge can be acquired, how one knows, how one does not know, and to what extent knowledge pertinent about someone or something can be acquired.[3][4]

這件事說明，知識論是硬貨，本體論是玄學，前者唯識，後者中觀，兩者命格不同，
