Lahas in Lamaism, are heavenly spirits who, long before the creation of the world, lived in unspeakable felicity, which was of an earthly nature. Above the earth there were twenty worlds inhabited by these beings, the highest four of which were so purified that their inhabitants lived without food. When the world was created many of these Lahas descended to it, and became so earthly they were subjected to its laws. When they ate of the fruits of this earth they became black, and the sun and moon were therefore created to give light to this .otherwise dark world. The human family, as also the sunken animal world, is indebted to the Lahas for their existence.
