To begin decorating a home temple, select a location that is easily accessible and well-ventilated. Then, using a decorative cloth, a wooden cabinet or shelf, and a statue or picture of your chosen deity, you can construct an altar or mandir. To create a serene atmosphere, add flowers, candles, and incense, and decorate the space with small statues or pictures of other deities. To improve the ambiance, add lighting such as string lights or lamps. Finally, keep the area clean and tidy to keep the temple space peaceful and welcoming.
