What are the specific chapters of Bhagavad Gita that should be read for the Shanti of the departed ancestors/ family members ?
Ninth chapter of gita is sufficient because it has following verse:
यान्ति देवव्रता देवान् पितृ़न्यान्ति पितृव्रताः।
भूतानि यान्ति भूतेज्या यान्ति मद्याजिनोऽपि माम्।।9.25।।
9.25. The votaries of the gods attain the gods; the votaries of the manes attain the manes; performers of sacrifices for the goblins attain the goblins; also the performers of sacrifices for Me attain Me.
As far as I know, people do not generally read Bhagavad Gita for Pitr Shanti.
However, I did answer to a similar question, which was on prayaschitta for not performing rites and that also comes under the category fo Pitr Shanti. The following activities are recommended for Pitr shanti, apart from Shraddha karma. These are mentioned in a book named "Pithru Poojanam" (there is no online link for this book, sorry), but you can read about the accomplished author Brahmasri Rajagopala Ganapaadi.
- paaraayana of Srimad Ramayana for 9 nine days
- paaraayana Srimad Bhagavatam for 7 days.
- Respective Veda paaraayana through qualified scholars
- Bathing in holy rivers after proper sankalpam for the sathagati of the departed
- Donating black till/sesame seeds or rice with sesame seeds or black urad dall to impoverished people
- Donating dress or food on the maasika days to poor people
- Donating food and dress for laborers
So far as I know,chanting of the whole Gita is done on the sraddha day in some parts of India, particularly Bengal. A brahmin is appointed especially for the paatha of Gita. I did not get any direct scriptural order as its cause.But I think Gita is chanted for Pitri-shanti on sraddha day because
- In the Gita-Mahtmya, Lord Vishnu says(Gita, Udbodhan,page 408):
Wherever is Gita read, all sacred places like Prayag appear there.All the rishis, yogis,Pannagas, Narada, Uddhava, the gopalas and the gopis appear there. I also appear there.
Bhagavan Visnu or Hari is known as destoyer of all sins("Sarvapaapaharo Harih") and bestower of Mukti("Mukum muktim dadaati iti Mukundah"). It is believed that our souls of our dead ancestors appear to accept pinda on the Sraddha day. I think it is believed following the Gitamahatmya that the presence of the teerthas, rishis, devotees and God Himslf will be more than enough for destroying all the sins of the departed soul and getting his or her the supreme upliftment.
- At the same time, Gita repeatedly says about the immortality of the soul. I think this also gives solace to the wards that their father or mother are still living at least in sukshnma form and so not lost forever.
But I repeat, these are local customs and beliefs and so vary from region to region. In Bengal, a copy of Gita is given to 12 brahmins along with some other daanas.
Thanks All, I got to read that chapters 7, 12& 15 for pitru Shanthi.
