The chatra or chhatra, also known under various translations including the ceremonial, state, royal, or holy umbrella or parasol, is a symbol of royal and imperial power and sanctity in Indian art and a symbol of holiness in Hinduism, Jainism, and Buddhism.
In India, the chatra was an ancient symbol of kingship and emperorship, representing both kingly power and righteousness.
It is also reckoned one of the ashtamangala, the eight holy symbols of enlightened sages and buddhas, in Digambar Jainism, Vajrayana Buddhism, and other Dharmic faiths.
[citation needed] More often, it is an emblem of various gods including Varuna, Ganesha (particularly during Ganesh Chaturthi), Revanta, Surya, Vishnu in his Vamana avatar, and Vishvakarman.
In Thai culture, the chatra developed into the white Royal Nine-Tiered Umbrella, part of the country's regalia.
