Kshetri are almost all Hindus as per 2011 Nepal census. Historically, they practiced Hindu polytheism and shamanism. They generally worship their clan deity (Kul Devta), friendly deity (Ishta Devta) and Khas Masto deities. Kshetri commonly have warrior like deities as Bhadrakali, Kalika Bhawani and different forms of Goddess Kali as female deity and Rudra, Veerbhadra (ferocious forms of Shiva) as male deity. Bhadrakali, a popular form of Goddess Kali, is the main deity of the Nepalese Army (previously Gorkhali Army) due to prevalence of Kshetri commanders. Worship to these deities were necessary before wars. There was a popular folk legend that the Chinese failed the strategic attacks on 1792 AD due to the effect of religious war cry of "Jai Bhawani". In the times of unification of Nepal, Kshetris were more rigid to worship of ferocious forms of Godess Kali and Lord Shiva. Amar Singh Thapa based on religious values developed Nishankalika flag after ceremoniously inviting Kalika Bhawani, ancestors, friendly deities and 49 Maruts to reside on the flag.
