As per Brhat Samhita, in Krta Yuga devatas could move freely between Swargaloga and earth. At the end of Krta Yuga when Treta Yuga was beginning a formless and nameless and invisible Satva started blocking the passage between the two worlds. The devatas and the bhulogas requested Brahma for the passageway to be cleared. Brahma pushes the Satva down and it fell on earth face down as Vastu Purusha with the head facing the north east direction and the whole body in a square formation. To prevent Vastu Purusha from getting up and blocking the passage again, different Devatas occupied the different parts of the body. Brahma himself occupied the centre. On the body of the Vastu Purusha a replica of Swargaloga can be created.
