As a purifier, Fire purifies everything in its Divine, Radiant Energy, making the event of Frashogard a reality. Significantly, Kai Siavux walked through fire to prove his piety to his father, Kai Kaus, just as Sita, in the Ramayana, walks through fire to prove her innocence after she is rescued from the evil Ravana. The link between the two is maintained through Fire as it enables the spirit to descend and function on the physical plane and it also purifies all matter into a spiritual state. The very goal of life is to transmute our physical bodies into the ethereal robes of Tanpasin, through the purification of the different Fires within ourselves, which will eventually enable us to become perfected and united with all the nine parts of our soul in Khaetwadath and thereby attain Frashogard. Through the mystic philosophy of the Gathas, we are taught to transmute matter into energy through the agency of Fire.
Fire is sacred and divine in all the religions.
It is a Divinity, worded differently in different Religions. True monotheism does not renounce the worship of the Amashaspands and Yazatas. In every monotheistic philosophy, we find inevitably a host of archangels and angels worshipped as the manifestations of the One Supreme Creator. Today, scientists are rediscovering these energies as different forms of the electromagnetic spectrum such as radiowaves, gamma rays, X-rays, microwaves, etc. which are the sustainers of the universe. In the Vendidad, which is the sacred law of Asho Zarathushtra, the main thrust is on how to keep the elements, especially fire, free from contamination.
