In the Tarkasamgraha, Pratyaksa is identified as the first and most fundamental Pramana (source of knowledge). It is defined as knowledge produced by the contact of a sense-organ with its object (Indriyartha-sannikarsa-janyam jnanam).
"Perception is that knowledge which arises from the contact of the senses with their objects."
For a perceptual experience to occur, the following chain of contact is necessary:
Annambhatta distinguishes between two psychological stages or types of perception based on the level of conceptual clarity:
This is the primary, immediate, and non-judgmental stage of perception. It is the awareness of an object without its names, classes, or attributes. We perceive the "that" (existence) but not the "what" (identity). It is pure, raw sensory data before the mind processes it into a concept.
This is the secondary, reflective, and judgmental stage where the object is perceived along with its attributes (Vishesana), such as its name, genus, and quality. Here, the object is recognized as "This is a jar" or "This man is fair".
| Feature | Nirvikalpaka | Savikalpaka |
|---|---|---|
| Nature | Non-relational / Indeterminate. | Relational / Determinate. |
| Content | Bare existence (the 'that'). | Attributes and identity (the 'what'). |
| Expression | Cannot be expressed in words. | Can be articulated in language. |
Perception is broadly classified into two categories based on the nature of the sense-object contact:
This occurs through the normal functioning of the five external senses (Sight, Smell, Taste, Touch, Hearing) and the internal sense (Manas/Mind). It is further divided into:
This involves contact that transcends ordinary sensory limits. It is typically subdivided in the Nyaya tradition into Samanyalaksana (perception of universals), Jnanalaksana (complicated perception), and Yogaja (intuitive perception of yogis).
Q: Is Savikalpaka perception always valid?
A: Not necessarily. While it is a stage of perception, if the attributes applied are incorrect (like mistaking a rope for a snake), it becomes Viparyaya (invalid knowledge).
Q: What is the role of Manas in Pratyaksa?
A: Manas acts as an internal sense-organ for perceiving internal states and serves as a coordinator that prevents multiple sensations from overwhelming the Atman at once.
