In Vastu Shastra the West direction is governed by Varuna. Gains and children — dining and study areas suit this direction.
Vastu works on balance rather than superstition: each of the eight directions carries an element and a natural function, and a room placed against that function creates friction you feel daily — poor sleep, money that never settles, arguments in the kitchen.
