Design the main door like a face: two shutters as the nostrils, two small niches as the eyes, two jharokhas as the ears, an Om or swastik as the tilak, and the threshold and upper frame as the lips. Ancient texts say such decoration multiplies the power of the main door many times.
Main door and the wall around it
Dussehra and Diwali are the best muhurtas for kilan.
Sagun is a swar vigyan technique that is learnt fully only in the complete swar training; in brief, the lamp is lit while holding the breath. A lamp lit in sagun burns far longer: a 100 g ghee lamp lit on Dussehra burned for 10 to 12 days and a 10 g lamp has burned for 27 days, so a desi cow ghee lamp in the South-East of the kitchen needs only 25 to 50 g of ghee a day. A conch blown in sagun while holding a wish drives all negative energy out of the house.
The small niches were made for lamps; they are the eyes of the door, and lamps placed in them open its eyes. The jharokhas beside them are the ears. Lamps must be lit in the niches on festivals such as Diwali, Dussehra, Holi and Raksha Bandhan, and in royal houses they were lit daily; a house whose eyes stay open keeps a right watch over everyone. If a door, even one in a wrong place, is decorated like this with small desi cow ghee lamps in the niches, its defects do not apply.
