Traditionally, there are said to be four ways of obtaining pratyaksha: indriya pratyaksha (sense perception), manas pratyaksha (mental perception), svadana pratyaksha (self-consciousness) and yoga pratyaksha (super-normal intuition). Correct indriya pratyaksha allows individuals to have truthful and right perceptions of the world around them and is considered a direct perception.
Pratyaksha is the first of the pramanas and is broadly divided into two types: direct perception, or anubhava, and remembered perception, or smriti. It can alternatively be divided into indiscriminate perception, or nirvikalpa, where perception of the object is made without recognizing distinguishing features; and discriminate perception, or savikalpa, where distinguishing features are observed. The indiscriminate perception (nirvikalpa) type of pratyaksha is crucial in Advaita Vedanta because it means that the Ultimate Reality, or Brahman, can be perceived without features when liberation into truth occurs.
