When Adrikā (Adrika), the celestial nymph, having been cursed or imprecated took birth at Añjana (Anjana) mountains in the form of a female cat, she became the wife of Keśarī (Kesari), the chief of the vanara (vanara; the monkey people). A piśāca (pishacha) or a ghoul named Adri was born of Adrikā, sired by Niṛṛti (Nirwiti). He is the kṣētraja santāna (khetraja santan; a kind of surrogate – a child born of one’s wife by another man or entity) of Keśarī and therefore Hanumān’s (Hanuman) step-brother.
