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, study, and devotion. Such yoga 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".
The Yoga Sutras of Patanjali 2.1 defines three types of kriya, namely tapas (ascetic devotion), svadhyaya (study of the self or the scriptures),and Isvara pranidhana (devotion or surrender to higher consciousness).
