The night which celebrates Shiva, who manifested himself, and is known as Swayambhu (self-created). It is a major festival of "overcoming darkness and ignorance" in life and the world.
The entire Yogic science emanated from Shiva and so everything we have is his blessing. On this night we celebrate his Divinity and all that he showers in Blessings on mankind.
This day and night at this special constellation we celebrate the Devine counciousness that is everywhere, in every atom and in all living beings as the live itself .
