Which direction should the home mandir face?
ideally in the north-east of the home, with you facing east or north while praying.
Vāstu tradition calls the north-east corner Īśāna, the direction of Śiva, and considers it the calmest and most sacred part of a home. That is why it is the first choice for a mandir. The worshipper usually faces east (towards the rising sun) or north, so the deities face west or south.
In flats and small homes this is often impossible, and that is perfectly fine. Choose a clean, quiet, respectful spot: not under a staircase, not in a bathroom wall, and preferably not in the bedroom. If it must be in a bedroom, a small curtain or cabinet door that you close at night is a common solution.
The śāstras value purity of mind and regularity far above exact compass points. A small shelf where you pray every day, with love, is better than a perfect corner that is rarely used.
