Veda

This Vidya occurs in the Chandogyopanishad (1.6.6-7)

Sa is the white shining of the Sun. Ama is the dark, the ultra-black. This is Sama. That golden person who is seen within the Sun has a golden moustache and golden hair and is golden even to the fingernail tips. His eyes are even as Kapisa-lotus. His Name is the High. He is above all evil and sin. He who knows this goes beyond all evil.

One who realises the Aditya-Purusha through this Vidya goes above sin and reaches Saguna Brahman. The golden Purusha within the Sun is the shining Self adorned with attributes and hence the Highest Brahman itself conceived of qualitatively.
