Samskaras or sanskaras (Sanskrit: संस्कार) has several context driven meanings in Indian philosophy and Indian religions. One of these is "mental impression, recollection, psychological imprint" and this meaning is the basis for its use in Hindu philosophies, particularly in the development of its karma theory.
According to various schools of Indian philosophy, every action, intent or preparation by an individual leaves a samskara (impression, impact, imprint) in the deeper structure of his or her mind. These impressions then await volitional fruition in that individual's future, in the form of hidden expectations, circumstances or unconscious sense of self-worth. These Samskaras manifest as tendency, karmic impulse, subliminal impression, habitual potency or innate dispositions. The theory of Samskara has also been used, in ancient Indian texts, to develop explanations for how and why human beings remember anything, and the impact these memories have on his sense of suffering, happiness and contentness.
The Sanskrit word saṃskāra (संस्कार) has various context-driven meanings that broadly refer to "the putting together, accomplishing well, making perfect, a form of solemn recognition and getting ready" and "mental impression, recollection". The first context is at the etymological foundation of Sanskara term for rites of passage, while it is the second context, as a form of disposition, impression or behavioral inclination, that is at the etymological root of Sanskara word as a psychological concept in Indian philosophies.
The concept of Samskara is also discussed as Vasana (Sanskrit: वासना vāsanā), particularly in the Vaiśeṣika school of Hinduism. Vasana also means "impression, inclination of anything remaining unconsciously in the mind".
Samskara, or Sankhara, is a significant concept across major schools of Hindu philosophy as well as Buddhism and Jainism. The schools of Indian philosophy differ on the specific mechanisms about how samskara operates at the subconscious level. For example, Buddhism considers samskara as "causal continua" while being consistent with its "there is no self, no soul" premise, whereas the Vedic traditions within Hinduism consider samskara as "relational properties" (an impression, mark, impulse, tendency or a form of psychological potential energy within) that rests inside the "self, soul" of every person. In Yoga, Vedanta and Nyaya schools of Hinduism, samskara constitute an affective and motivational field that contributes to the value structure within the person. They subconsciously or consciously endorse the basic inner drives that propel a human being in future action, future premises, future thoughts or future judgments.
