Vasana

Vasana, in Indian philosophy, is a Sanskrit term meaning a latent impression, tendency, or desire formed by past actions and experiences. It is commonly used in Hindu traditions such as Vedanta and Yoga to describe mental impressions stored in the mind, often said to reside in the subconscious or in the storehouse of memory (chitta). Vasanas arise from past karma and samskaras and can be wholesome or unwholesome. They operate beneath ordinary awareness, shaping present thoughts, preferences, and reactions unless consciously examined.

As a concept, vasanas are not the will itself but the predispositions that bias perception and choice. They bind the individual to cyclic existence (samsara) by reinforcing attachment, aversion, and craving. Liberation or freedom is often described as the gradual weakening or dissolution of vasanas, so the mind becomes less governed by conditioned impressions. This is pursued through ethical discipline (yama and niyama), meditation, self-inquiry (atma-vichara), discrimination (viveka), and other practices aimed at revealing the true Self (atman) or pure consciousness.

Different schools offer nuanced views. Advaita Vedanta emphasizes the ultimate removal of vasanas to reveal non-dual awareness, whereas Yoga presents methods to quiet and transform vasanas, leading to steadier concentration and discernment. In contemporary usage, vasana is also employed to describe habitual patterns or latent tendencies in daily life, with emphasis on gradual transformation rather than abrupt change.
