Kalpa (Samskrit : कल्पः) not to be confused with Kalpas defined by Kala pramana (time) is a part of the Shad Vedangas. They are called as Sutragranthas consisting of a group of texts that relate specifically to aspects of conduct of Vedic yajnas or Shrauta yajnas, their procedural and result explanations, measurements involved and associated dharmas. Usually described as the "arms of Vedapurusha", they systematically codified the ceremonies given in the Brahmana texts of the Vedas referred to as manuals for karmakanda or yajna related activities.

Introduction

The origin of Kalpa was for the organization of all the extensive rituals described in Vedas (वैदिककर्मकाण्डः | Vaidika Karmakanda). Kalpas are classified under the Shad Vedangas. They include the contents directly mentioned in Brahmanas and Aranyakas, presented in a systematic manner, explaining those not mentioned explicitly in the Brahmanas and omitting others not directly related to a particular yajna or ceremony.
