Kriyā (Sanskrit क्रिया, "action, deed, effort") most commonly refers to a "completed action", technique or practice within a yoga discipline meant to achieve a specific result. The Yoga Sutras of Patanjali 2.1 defines three types of kriya, namely asceticism, recitation, and devotion to the lord. The yoga of such actions is called kriya yoga.
Kriyā is a Sanskrit term, derived from the Sanskrit root, kri, meaning "to do". Kriyā means "action, deed, effort". The word karma is also derived from the Sanskrit root √kṛ (kri) कृ, meaning "to do, make, perform, accomplish, cause, effect, prepare, undertake". Karma is related to verbal proto-Indo-European root *kwer- "to make, form".
