The third part of Sandhya is the Suryopasthana. It is a prayer for forgiveness, mercy and grace. I did wrong actions. These are Vedic hymns addressed to the sun in the morning, noon and evening. The sun is the intellect in man.
Ignorance is the night.
Knowledge is the light. When you rise up from the darkness of ignorance, when the eye of intuition is opened through the grace of Gayatri, the Blessed Mother of the Vedas, you attain eternal bliss, supreme peace and immortality. It is that divine light which dispels delusion and the darkness of ignorance. It is that adorable splendour with which the world is glowing. It is that holy lustre which graciously fills the heart of a devotee with eternal bliss.
