If it cannot be moved
A study in the south-west sits in the heaviest corner, which the tradition reads as pressure rather than concentration. The remedy is the same: turn the desk so the reader faces east or north, and keep the room’s north-east light.
What the ನೈಋತ್ಯ governs
The south-west — Nairutya — is the earth corner: the heaviest, most grounded part of the plan. It is where the tradition puts what should not move, which is why the master bedroom and the structural mass belong here and water does not.
Where the ಅಧ್ಯಯನ ಕಕ್ಷ belongs
A study is placed for concentration and for morning light, which puts it in the same corner family as the pooja room. Seating direction matters as much as the room here: the tradition seats the reader facing east or north.
