Gurupurnima is the festival of Light.
That light, that flame is Parabrahma, the Supreme. Without that Light the darkness of ignorance cannot be removed. Today we pray to the masters. Without their blessing liberation is not possible.

Gurupurnima is the day of the Guru, the highest principle in the world.The divine principle of Guru Tattva removes the darkness and illuminates everything. It is the celebration of wisdom and knowledge. You should be like a flame in the world and whoever comes to you shall get light from you. Let flow the river of Love. When you come somewhere, light and love shall come, too.
