Kalpa (Sanskrit: कल्प) means “proper, fit” and is one of the six disciplines of the Vedānga, or ancillary science connected with the Vedas – the scriptures of Hinduism

This field of study is focused on the procedures and ceremonies associated with Vedic ritual practice

The major texts of Kalpa Vedanga are called Kalpa Sutras in Hinduism

The scope of these texts includes Vedic rituals, rites of passage rituals associated with major life events such as birth, wedding and death in family, as well as personal conduct and proper duties in the life of an individual

Most Kalpasutras texts have experienced interpolation, changes and consequent corruption over their history, and Apasthamba Kalpasutra ancillary to the Yajurveda may be the best preserved text in this genre

Kalpa Sutras are also found in other Indian traditions, such as Jainism
