Best placed in the পশ্চিম
West is the accepted second placement for a master bedroom and is read as gains that settle after effort. The head of the bed goes to the west or south.
What the পশ্চিম governs
West is Varuna’s direction, associated with gains that arrive late and with stability after effort. It takes weight comfortably, and it is one of the two directions the tradition is relaxed about for utilities.
Where the মুখ্য শযনকক্ষ belongs
The master bedroom is meant to sit in the heaviest, most settled part of the house, on the theory that the person carrying the household should sleep where the building is most grounded. It is a placement about stability rather than energy.
