Also spelled Sankalpa, it's a Sanskrit word meaning "resolve" or "intention," as in the intention to achieve the desired goal. A person practices Samkalpa when they vow to perform a particular practice for a specific length of time, at a specific time of day, in a specific place, etc. Although this initially referred to a spiritual practice, some people have extended this to any such vow that requires a regular practice, such as a vow to regularly exercise.
