1)Southwest zone is named as a combination of the shrungarshala of south and the rangshala of the west ,so it is very vital zone.It contains the strong earth element which enriches the life by stability-support and significance to the life.The divine seed of earth element is seeded in the southwest zone of the central brahmasthan by ritual of Vaastu Nabhi ;where the soul of earth element gets rooted in the format of house.When the auspicious stone is placed in the southwest zone ,it gets a divine connectivity to the central sun element-ruby rooted in the brahmasthan which contains the Vastu Nabhi -soul of earth element.When the zones are connected to the Brahmsthan,they automatically receive the power-energy-strength through the supply of brahmand-lahari =the essence of Prana. To conform this sacred relationship with brahma ,the ritual of ratnadhyay has immense importance.
