In Rigveda, agni is called 'pavakka' which means pure. Therefore, lighting a diya at our home helps create a great sattvik ambience and ensures that everything is good, right, and pious. The lit diya activates the positive aura around us.
Diyas should remain lit throughout the night. Thus, begin lighting diyas after the Lakshmi puja to welcome her into your home. Keep the diyas lit throughout the night to ensure that darkness and negative spirits do not enter your home.
According to Hindu mythology, it is thought that there are 13 diyas that one must light in their house and pray for good health and prosperity during Diwali and Dhanteras.
We should always light a lamp in our Puja room daily, always light it either in the early mornings or during the evenings. It's not that only girls should light, even boys can light a lamp in Pooja's room.
Always Place Diyas And Agni Kund in the Southeast direction. You can also place the diyas in the east or the north. Placing them in the east is believed to bring health to the family, whereas placing them in the north brings wealth. Avoid placing it South
Lighting diya outside your home is a good idea, especially if you have toddlers and pets. Lighting the diya or lamp ensures that no one gets hurt and personal property is not destroyed. It is much safer to light diya outside the vicinity of your space.
