FAQs
It teaches that the Supreme is intrinsically pure and attributeless, but appears to take on qualities due to association with upādhis (limiting conditions), just as a clear crystal seems red when placed near a red coloring base.
The verse supports viveka (discriminative insight) used in Yoga and contemplation: the practitioner learns to distinguish the pure Self/Ishvara from the changing upādhis—body, mind, guṇas—thereby stabilizing meditation on the unconditioned reality.
By emphasizing one Supreme reality that only appears diversified through upādhis, it aligns with the Kurma Purana’s non-sectarian synthesis: Shiva and Vishnu can be understood as manifestations or designations of the same Paramapurusha rather than competing absolutes.
