In Buddhism
Tibetan Buddhism (Vajrayana or tantric Buddhism)
Rātrikā (रात्रिका) refers to a type of “sickle” and represents one of the items held in the left hand of Heruka: one of the main deities of the Herukamaṇḍala described in the 10th century Ḍākārṇava chapter 15. Heruka is positioned in the Lotus (padma) at the center; He is the origin of all heroes; He has 17 faces (with three eyes on each) and 76 arms [holding, for example, rātrikā]; He is half black and half green in color; He is dancing on a flaming sun placed on Bhairava and Kālarātrī.
Note: This is a “short club” (daṇḍikā) and a “dātrikā sickle” in the Ḍākārṇava (10.47 c) and (29.4 c).

Tibetan Buddhism includes schools such as Nyingma, Kadampa, Kagyu and Gelug. Their primary canon of literature is divided in two broad categories: The Kangyur, which consists of Buddha’s words, and the Tengyur, which includes commentaries from various sources. Esotericism and tantra techniques (vajrayāna) are collected indepently.

Rātrika (रात्रिक) in the Sanskrit language is related to the Prakrit word: Rāia.
Sanskrit, also spelled संस्कृतम् (saṃskṛtam), is an ancient language of India commonly seen as the grandmother of the Indo-European language family (even English!). Closely allied with Prakrit and Pali, Sanskrit is more exhaustive in both grammar and terms and has the most extensive collection of literature in the world, greatly surpassing its sister-languages Greek and Latin.
