Best placed in the పశ్చిమ
West is a settled, accepted placement for a child’s room and is often preferred for older children — the tradition reads it as steadiness after effort, which suits exam years.
What the పశ్చిమ 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 బచ్చోం కా కక్ష belongs
A child’s room is read differently from the master bedroom: it wants movement, growth and morning light rather than weight. The tradition is also more relaxed here, and school-age and adult children are often placed differently.
