Pramāna means evidence and means of knowledge. 

• Pramāna is the basic notion of Indian epistemology.
• It deals with means that can lead to knowledge of Indian philosophies. 
• It's a theory of knowledge that deals with one or more trusts and the validity of acquired knowledge.
• Pramana is concerned with how proper information can be learned, how one knows what one does not know, and to what extent one can acquire knowledge relevant to someone or something.
• There are six Pramāna as correct means of true knowledge.
• For Nyāya doctrine, all four Pramanas, perception, inference, verbal testimony, and comparison are valid forms of knowledge. 
• Inference (anumāna) is defined as using reason to arrive at a new conclusion and truth from one or more observations and earlier truths.
• There are three central Pramāna that are universally accepted: Perception, inference, and word. 
• The number of these six epistemically reliable and legitimate means of knowledge varies throughout Indian philosophical traditions.

Thus, according to pramāna theory both dialogical and philosophical discourse, it furnishes the required grounding for the thesis to be backed up by a certain means of knowledge,  It enables us to succinctly summarise the observations, and that stem out of the analysis, in the form of anumāna or nyāya prayoga.
