According to Hinduism, a human being has five sheaths. They are, respectively.
1.Annamaya Kosa, which is made from the essence of food,
2. Pranamya Kosa of Breath,
3. Thoughts’ Manomaya Kosa
4.Vignanamaya Kosa, of Knowledge and Understanding
5.Bliss’s Anandamaya Kosa.
Each of these is nurtured by their respective attributes/sources of Being, and they form the Living Human being. When someone dies, we see a lifeless body that was nurtured by Food at the Annamaya Kosa Level, by the essence of Food.It lingers around the place of death until the twelfth day after death.
Until the twelfth day Tharpana, known as Kuzhi Tharpan, is performed and a small pit is dug, preferably near the house where the death occurred.Ceremonies for death are held until the 12th day, with the thirteenth being Purification, not only for the satisfaction of the Annamaya Kosa, but also for the other Kosas, Prana, Vignana, Manas, and Ananda, the latter reminding the Self of its Eternal Nature.
This is ensured by the mantras recited over the course of the twelve days.
Following these rituals, the Subtle body, Sukshama, enters the Pithru loka without the Physical body.
Even after rebirth, the Subtle body retains the remnants of the actions performed.
Both men and women have equal rights in the Vedas, which means that the liturgical process can be performed by the deceased's family members, sons and daughters, parents, siblings, and so on. If no one has a family member, then this best work can be done by anyone.
The head should be pointing north, and the feet should be pointing south. This is known as Dakshinabhimukh.
After the Agni Sankar rites, you can prepare normal meal at home, according to Vedic tradition.
There is no similar structure in the Vedas.
Nowhere in the Vedas is there any reference of such a system. It is a widespread superstition.
According to Hinduism, Antyesti Sanskar (Last Rites) is the last sanskar of a human being. There is no sanskar or ritual left for any human being after this. In all religions, a dead body must be disposed of. Arya Samaj accomplishes this by burning the deceased body on a wood fire and offering a generous amount of Ghee and Havan Samgri. For this Antyesti Sanskar, the process is carried out in the manner of a Yagya, with the chanting of selected Vedic Mantras.
