In the study of तत्त्व मीमांसा (Tattva Mimamsa), the authenticity or validity of proofs (pramāṇas) holds a central position, as it is through valid means of knowledge that one attains true understanding of reality. Pramāṇas are the tools or methods through which knowledge is acquired, and their authenticity ensures that the knowledge obtained is accurate and reliable. Pramāṇas can be broadly defined as the instruments or sources of knowledge that lead to valid cognition. The Mimamsa philosophy emphasizes that knowledge should not be based on mere assumptions, conjectures, or hearsay, but must be derived from authenticated means. The authenticity of pramāṇas is evaluated on the basis of their ability to produce true and non-erroneous knowledge. A pramāṇa that produces knowledge free from doubt and error is considered valid and trustworthy. There are several types of pramāṇas recognized within Indian philosophical traditions, and their authenticity is scrutinized according to certain criteria. The classical Mimamsa system primarily accepts three pramāṇas: perception (pratyakṣa), inference (anumāna), and verbal testimony or verbal revelation (śabda). Each of these pramāṇas is subject to specific conditions to be considered authentic. 1. Pratyakṣa (Perception) Perception is the direct, immediate knowledge that arises from the interaction of the senses with objects. The authenticity of perception depends on the absence of defects such as illusion, error, or hallucination. A perception is valid when it arises from a clear, unobstructed sensory encounter with the object and is free from misinterpretation. For example, seeing a pot on the ground directly is a valid perception if there is no obstruction or misperception like mistaking a round stone for a pot. Mimamsa philosophers emphasize that perception is considered valid only when it is *nirvikalpa* (indeterminate) and *savikalpa* (determinate), meaning it must be both uncontradicted by prior knowledge and capable of being conceptualized within the mind. The pramāṇatva (validity) of perception also requires that the senses are functioning properly and that the object is present and external. 2. Anumāna (Inference) Inference is the process of deriving knowledge about something not directly perceived based on reasoning and prior knowledge. The authenticity of inference depends on the reliability of the logical structure and the premises used. Inference follows
