Best placed in the ઈશાન
The north-east is the classical study placement, sharing its logic with the pooja room — light, clarity and the first sun. Keep the desk clear of the corner itself and face east while reading.
What the ઈશાન governs
The north-east — Ishanya — is the most protected corner in the whole mandala. It carries water and belongs to Shiva, and every school agrees on the same instruction: keep it light, clean, open and low. Almost every serious Vastu fault is some version of loading this corner.
Where the અધ્યયન કક્ષ 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.
