Adi Shankara

The Atman, the sun of knowledge that rises in the sky of the heart, destroys the darkness of the ignorance, pervades and sustains all, and shines and makes everything to shine.

one who, renouncing all activities, who is free of all the limitations of time, space and direction, worships their own Atman, which is present everywhere, which is the destroyer of heat and cold, which is bliss eternal and stainless,
