lesya
(Sanskrit: "light," "tint"), according to Jainism, a religion of India, the special aura of the soul that can be described in terms of colour, scent, touch, and taste and that indicates the stage of spiritual progress reached by the creature, whether human, animal, demon, or divine. The lesya is determined by the adherence of karmic matter to the soul, resulting from both good and bad actions. This adherence is compared to the way in which particles of dust adhere to a body smeared with oil
