Vastu Purush Mandala having 45 Devtas and Asuras.
Satya – the Creator of Goodwill: Energy field, next to Surya, in the East direction, is known as Satya. We do not find any dev named ‘Satya’ in any vedic literature. However, description of a dev–’Satyen’—as the primary dev for (developing) good will and status while establishing any new concern has been found.
This dev was invoked for almost all the establishments in ‘Panini-kaleen’ (in the period of Panini) India. He is worshipped as the one responsible to establish the authenticity, credibility and reputation of attributes. Although rarely, but we get written scriptures for that.
