"Throughout the past 1,200 years of so, there have been approximately 160,000 documented cases of people turning into literal lightbodies.
One of the first documented cases involved a saint that went by the name of Padmasambhava, and achieved light body status along with many of his disciples. On his way to becoming a light body, he was also able to fly in the air as well as transform his body into forms that would frighten evil spirits and demons, while transforming them into Dharma protectors.
He was also the first (of many) to leave his footprint embedded deep into stone before transforming into a light body. Many of these footprints are still visible in these same Himalayan rocks, today!"
