Vastu is a Science and every practice postulated by Vastu, followed for thousands of years are based on scientific facts. The earth is tilted at an angle of 22.5 degrees on its axis. This corresponds to the North East direction. We receive magnetic energy from the North and Solar energy from the East. Hence the North East is an optimal position to receive the most positive and beneficial energy to enhance all facets of our lives.This promotes better health, state of mind, positive energy at home, health and prosperity.
Hence the practice came about, of placing the god's room in this region, to enhance the energy levels and positivity. So we do not place the toilet, store room, utility room, clutter and heavy objects in this region. Ideally it is left free or some space is left here during construction. The best location for positive energy emanating objects, bells, bamboo plants, windbells and windchimes, puja room, god's photos is the North East, emphasizing the Vastu principles of positive energy field creation using optimal directional forces.
