The South belongs to Yama, the god of justice and messenger of death, who rides a buffalo and holds a danda (rod). Its planet is Mars (Mangal) and its stone is moonga (coral); it is the zone of complete relaxation and sleep and rules the world of departed ancestors.
South
From about 4 to 4:30 pm the Sun reaches SW and the energy begins to cool and stabilise the mind; it strengthens relationships and skills, motivates hard work and gives stability to every work. It suits bedroom, drawing room, tijori and heavy items, subject to Rahu-Ketu checks.
South-West zone of the house
Photos of departed ancestors go in the South-West, but never inside a bedroom; family photos of the living go anywhere except the South and SSW zones, on a wall where their faces look North.
Ancestors: South-West, outside the bedroom. Family photos: South wall, not in the South or SSW zones
Each zone suits a particular worship: North for Saraswati and Ganesh, NNE for pranic sadhana, NE and East for meditation, South for Hanuman and Devi, West best of all, while SE, SSE and SSW suit no puja.
Best: West. By deity: North, NNE, NE, East, South, SW (ancestors), WSW, WNW, NW, NNW. No puja: SE, SSE, SSW.
Photos of departed family members (with garlands) should face South, the direction of Yama; they can hang in the South, SW, SSW or WSW zone, but never in a bedroom or drawing room.
Faces South; zones such as S, SW, SSW, WSW; not in bedroom or drawing room
No, it is not right at all.
All of them, photos of ancestors, gods and family and statues of deities, will be taught in detail later, including where each goes and which way it should face. Even the wider world is confused about which way ancestors' photos should face.
No. Ancestors' photos should not be put inside the bedroom, even when the bedroom is in the South-West.
Yes, they also represent a planet and should be placed correctly. A consecrated God's photo should face North or East, or West if that is not possible, but never South; South-facing is for the photos of ancestors who have left this world.
