 Broadly, all objects of knowledge are classified into two realities based on the ways in which right-cognition (pramāṇa) engages with its object. They are either directly accessible (pratyakṣa), which constitutes objects that are obvious to cognition, or they are directly inaccessible (parokṣa), which constitutes objects that are occulted, or obscured from cognition. A directly accessible object is principally known by a direct perceptual right-cognition (pratyaṣa-pramāṇa), whereas a directly inaccessible object is principally known by an inferential right-cognition (anumāna-pramāṇa).
