सङ्कल्प - Samkalpa - is a Sanskrit word meaning a resolution; a free will or a determination. The word Sankalpa itself means good intention, an oath or a resolution to do something, a solemn pledge to do something good.All Yagnas and worships are accomplished after taking a vow for its performance. Sankalpa is nothing but an expression of feeling which the Saadhaka (doer) has for accomplishment of a Saadhana (task). By making a pledge a person becomes committed towards the accomplishment of his goal. Taking sankalpa as also oath means becoming committed to something and making Paramatma /Ista-Devata witness of it.
