Vijnana

Vijnana (consciousness, discernment) is a fundamental concept in Buddhist philosophy referring to awareness of objects.

Overview

Vijnana (Pali vinnana, Sanskrit vijnana) literally means “knowing” or “discernment.” It refers to the six types of consciousness: eye-consciousness (chakkhu-vinnana), ear-consciousness (sota-vinnana), nose-consciousness (ghana-vinnana), tongue-consciousness (jivha-vinnana), body-consciousness (kaya-vinnana), and mind-consciousness (mano-vinnana). Each type of consciousness arises when a sense organ contacts its corresponding object.

Philosophical Context

Vijnana is one of the five aggregates (khandha) and one of the twelve links of dependent origination. In the Madhyamaka tradition, vijnana is empty of inherent existence — it arises dependently on sense organs and objects. In the Yogacara tradition, vijnana is analyzed into eight types, with the alaya-vijnana (storehouse consciousness) serving as the foundation for the other seven. The Heart Sutra declares: “Form is emptiness, emptiness is form… there is no eye-consciousness, no ear-consciousness,” pointing to the emptiness of all types of consciousness.

Interpretations

In Theravada Buddhism, vijnana is analyzed in the Abhidhamma as a series of momentary states of awareness, each arising and passing away. In Mahayana Buddhism, vijnana is understood as a continuous stream that carries karmic seeds (bija) from one life to the next. The Yogacara school’s analysis of the eight consciousnesses provides a detailed map of mental processes, including the subconscious storehouse.
