Tibetan Mahakala mask given some vector treatment.
According to the website Karma Samten Ling Buddhist Centre : “Mahakala, a wrathful deity, is considered to be the fierce and powerful emanation of
Avalokiteshvara, the bodhisattva of compassion.”
“This … deity … defend(s) the Dharma from corruption and degeneration and from forces hostile to it; to keep the site of the ritual free from impure thoughts and actions; to guide and protect the individual practitioner from all kinds of deception and delusion; bestow the power to overcome life struggles; and to eliminate one’s obstacles and impediment that hinders.”
“Everywhere, countless lives and properties are lost in wars, natural
disasters and viruses. With the blessing and power of Mahakala, countries would become prosperous and one would be kept away from these obstacles and misfortunes.”
