− | The word ‘pratyaksha pramana’ means first hand evidence. Pramana denotes sensory perception. Here the individual gains knowledge through the medium of sense organs. It is considered as the most primary and important tool for diagnosis, prognosis, inference, conclusion and treatment of the diseases according to [[Ayurveda]]. It is the means of acquiring knowledge through the medium of sense organs and self-experiences. The direct clinical examination of patient (pratyaksha pariksha) is vital for diagnosis of disease. It also involves the examination and assessment of complications ([[upadrava]]), and prognosis or impending death ([[arishta]]). The pacifying factors ([[upashaya]]) and aggravating factors ([[anupashaya]]) are observed by direct examination. Thus it forms the basis for anumana pramana.

Thus, the direct observation made by the examining physician plays key role in diagnosis and treatment. With the advent of advancement in the field of diagnostic technologies, patient management has been revolutionized. The invention of various radiological and imaging techniques like X-ray, MRI, CT Scan, Angiography, USG and Doppler, endoscopy, laparoscopy techniques has changed the face of modern medicine. These all help to assess and witness the internal human pathology that otherwise can escape the physical examination. These are the examples of extended application of pratyaksha pramana as they help to visualize the body mechanism. The development pertaining to interactive learning and teaching techniques is also an application of pratyaksha pramana. The practical or hands on sessions in different workshops are examples of the same. |

− | The scope of direct observation is very limited for an individual, as there are infinite and unknown phenomena that cannot be assessed by pratyaksha alone.[Cha.Sa.[[Sutra Sthana]] 11/7] There are hindrances to acquirement of knowledge through the medium of pratyaksha as mentioned earlier. Thus, many times it is necessary to combine the knowledge from all sources like authoritative statements (aaptopadesha), analogy (upamana), inference (anumana), logical reasoning (yukti) to acquire correct knowledge regarding any phenomena. One who might have practical experience regarding different treatment procedures and surgical interventions, but lacks theoretical and fundamental knowledge cannot succeed in endeavours and does not gain validation from peers and authority. [Su. Sa. Sutra Sthana 3/49]<ref name=Susruta/> Thus, the knowledge of pratyaksha should be combined with the theoretical study to obtain precision and proficiency in treatment.
