The representative planet for the northwest direction is Moon (Chandra) and the corresponding lord for the northwest direction is Lord Vayu. The planet Chandra can prove to be either advantageous or disadvantageous for the inmates. This planet can bring both positive and negative energy to the house. Northwest direction is the bearer of creating either friendships or enmity in the life of inmates. The wrong usage of the northwest direction will invite troubles like physical illness, ill-temper, instability, restlessness and more enemies. On the contrary, if this direction complements Vastu principles, there are chances one will have more friends who will prove to be beneficial to the inmates. Keep the walls in the northwest direction lower than the walls in the northeast direction in the balconies and porches of the house to make it defect-free.
