Brahman is changeless existence. It alone exists as the SELF. When Brahman was in that state, prema entered and immediately creation was willed, taking the Virat Purusha form. The Virat Purusha separated Purusha and Prakriti and the two began to shower prema; thus man & women came into existence. Prema is the origin and primordial cause of creation. It inspired Brahman to create. Brahman separated himself into two. One become truth and one love. Sathya became the goal and Prema the path.
