Vasana
वासना (vasana)
Latent tendency - the accumulated residue of samskaras, forming the deep dispositions that drive behavior.
Where samskara names a single impression, vasana names the accumulated residue of many such impressions, forming a deeper, more stable tendency or disposition that shapes behavior often without the person's conscious awareness of its source.
A person's characteristic way of responding to conflict, to praise, to loss, is, in this framework, less a fixed personality trait than a vasana: a deep groove worn by countless repetitions, old enough that its individual origins have been forgotten even as its pull remains strong.
Because vasanas operate largely below conscious awareness, working with them tends to require more than intellectual insight. Sustained practice, over time, is understood to gradually weaken even long-held vasanas, though the classical texts are candid that this is slow work, not a single realization away.
