Apne Dharam ko jaano.
Being a doctor or well educated doesn't means that we will start questioning our traditions and customs without understanding them. There is pure logic behind all rituals of our religion.
The Terahvin ceremony is an important tradition in Hinduism, as it is believed that performing this ritual can help the soul of the departed person to attain peace and move on to the afterlife.
Hindu funeral rites typically last for a period of 13 days, which is commonly known as the "Hindu funeral rites 13 days ceremony" or the "terahvin." This period is a time for mourning and honoring the deceased, and it is believed that the soul of the departed remains in the earthly realm for Hindu funeral rites 13 days before departing for the afterlife.
