Naga is the Sanskrit and Pali word for a deity or class of entity or being, taking the form of a very great snake—specifically the king cobra, found in Indian religions, namely Hinduism, Buddhism, Jainism and Sikhism. A female naga is a nagi or nagini.
Cambodian naga possess numerological symbolism in the number of their heads. Odd-headed naga symbolise the “Energy, Infinity, Timelessness, and Immortality”. This is because, numerologically, all odd numbers come from One (1). Even-headed naga are said to be “Female, representing Physicality, Mortality, Temporality, and the Earth.”
