Direct Perception
The first pramana — knowledge produced through direct contact of the senses with objects, classified as ordinary (laukika) and extraordinary (alaukika).
Pratyaksha: Direct Perception
Pratyaksha (perception) is knowledge produced through contact of the senses with objects of the world. This contact must be clear — when in twilight one perceives a rope as a snake, it is false and invalid perception. Nyaya classifies perception as laukika (ordinary) and alaukika (extraordinary).
There are five ordinary external perceptions: hearing, touching, seeing, tasting, and smelling. Extraordinary perception is based upon association and intuition and includes perception of the qualities of soul, thought, desire, aversion, pleasure, pain, and cognition.
Ayurveda uses both ordinary and extraordinary perception as diagnostic tools. For instance, when a patient has a fever, ordinary pratyaksha includes measuring temperature with a thermometer, observing reddened skin, and feeling the heat. Extraordinary perception through association and intuition is developed through persistent yogic and Ayurvedic practice in daily observation.
