“Barwa” means twelfth, the 12^th day of mourning. According to hindu beliefs, the journey of the soul takes 12 days to leave this planet and become one with its ancestors. In its human incarnation the soul goes through 16 stations or rites of passage (sanskaras) from conception to cremation. After cremation, last station or rite of passage(antim sanskara) and immersing  the ashes in a river/lake, a puja is performed on the 12^th day for the dear departed one's soul.
The future of the soul depends on the person’s deeds in this world – good and bad. If good deeds outnumber the bad the person attains “moksha” – liberation form the cycle of birth and death. If not, then the person is reborn. When our near one passes away we do feel sad, but with prayers and donations on behalf of the soul, we add to the good deeds of the deceased and help them attain moksha. The family therefore does the following on each of the 12 days and then monthly for the a whole year; Take a bath in the morning, say prayers, feed animals like cows, crows, dogs and brahmin( priest) or a needy person before eating.

Since people may find it difficult to do it every month, they can instead combine the 12 monthly offerings into one offering on the 12^th day. Food, clothes and cash are offered to the brahmin(s) doing the puja. During the puja 42 dough balls are made which is symbolism for the offerings to cows, crows, dogs and other living beings for each of the 12 days and the the 12 months. After the puja they are given to the animals or dispersed in a water body.Havan ceremony is performed. Fire worship purifies as it burns away everything. Every time swaha is recited, offering has to be made of rice and ghee. Sweet Prasad is offered. Nani's favorite food items were prepared for the brahmin’s meal. Food is also  offered in memory of ancestors and their names were recited to pray for them along with nani's who will be re-uniting with them.
It has been mentioned in Bhagavad Gita that Lord Krishna used to worship and feed cows everyday, for his ancestors..
Peace prayer, Gayatri mantra, and Mahamrityunjaya mantra were recited.
Om Namo Bhagvate Vasudeva is mantra for Lord vishnu
Mahamritunjaya for Shiva
Gayatri mantra for Godess Gayatri
Peace prayer was chanted.  Intention of the prayer was set by saying the name of the soul (nani) and name of person( Arnav) who is praying. Since the journey to moksha needs the soul to be resolute, the nearest ones offer to give up something in order to strengthen the soul’s resolve. Yashasvi(mom) gave up eating eggplant. And Karishma( Barkha maasi) is gave up tea. Both also resolved  to fast on the 24 “EkaDashi” days in the coming year. Ekadashi is the 11^th day of each moon phase. On Ekadashi days, both will observe a grain-free fast and only consume fruit/juices/milk. After the 24 fasts the fruits will be offered and distributed at the temple.

The family expressed gratitude for all the sacrifices nani made. Moment of silence was observed. Hemant Maharaj sang a beautiful poem in praise of mothers.

Burn him not up, nor quite consume him, Agni: let not his body or his skin be scattered,
O all possessing Fire, when thou hast matured him, then send him on his way unto the Fathers.
When thou hast made him ready, all possessing Fire, then do thou give him over to the Fathers,
When he attains unto the life that waits him, he shall become subject to the will of gods.
The Sun receive thine eye, the Wind thy Prana (life-principle, breathe); go, as thy merit is, to earth or heaven. Go, if it be thy lot, unto the waters; go, make thine home in plants with all thy members.

— Rigveda 10.16
