Pitru

http://en.wikipedia.org/wiki/Pitru_Paksha

The word 'pithri' literally means father, but it refers to all one's anacestors. According to our mythology, the dead mortals will reach the abode meant for such souls, if they have had virtuous deeds to their credit. All such manes absorb with the seven deities there, named 'Pithris'. The names of these deities are

1. Kavyavaaha, 
2. anala, 
3. Soama, 
4. Yama, 
5. Aryama, 
6. Agnishvaaththa and 
7. Barhishada. 

It is for the purpose of securing a place for parents and themselves as well in this abode that people observe penances and practice several austere procedures.

Number of generations

The number of generations that get liberated depends upon the stature of the devotee. In Srila Prabhupader Upadesamrta (“The Nectarean Instructions of Srila Bhaktisiddhanta Sarasvati Prabhupada”), the following fact is presented by Srila Bhaktisiddhanta Sarasvati Thakur.

1. “When a great saint, a pure devotee, appears in a family, his ancestors and descendants for a *hundred* generations are elevated.
2. When a devotee of middle stature (madhyam bhagavat) appears in a family, his ancestors and descendants for *fourteen* generations are elevated.
3. When a neophyte devotee appears in a family, his ancestors and descendants for *three* generations are elevated.”

1008

Once Vasistha invited his arch enemy Vishwamitra for a feast on a Srardha day. On the day of Srardha, the departed souls are propitiated. Brahmins and saints were fed on the day. The guests are worshipped as the representatives of the departed souls. Vishvamitra promised to participate on one condition. He insisted that he must be served with 1008 curries (side dishes). Vasishta knew what he was up to. He told him that he would inform his ‘home minister’ Arundhati as she was in charge of the guests.

Vasishta informed Arundhati the condition laid by Vishwamitra. She did not bother. On the day of Srardha , Vishwamitra came and sat at the dining hall. But to his disappointment he saw only 10+ curries on the plate (plantain leaf). When he angrily questioned Vasishta, he told him to put the question to Arundhati as she was in charge of the ceremony. Before Vishwamitra questioned her, Arundhati recited a popular sloka (couplet) which made Vishwamitra speechless.

What did Arundhati tell him?
कारवल्लि शांत चैव वज्र वल्लि शतत्रयं
पनसं षट् शतंचैव श्रार्धकाले विधीयते

Kaaravalli satam chaiva vajra valli satatrayam
Panasam shat satam chaiva sraardhakaalE VidhiiyatE

“If someone serves at the time of Srardha, 

1. https://en.wikipedia.org/wiki/Momordica_charantia is equal to 100 items,
2. https://en.wikipedia.org/wiki/Cissus_quadrangularis that is equal to 300 curry items 
3. and https://en.wikipedia.org/wiki/Jackfruit that is equal to 600 items. 

That is the rule for the ceremony.”

She served these three vegetable dishes along with 8 more items on the plate. So it came to 1008 items. Vishwamitra was happy at the explanation from the chastest woman in the world.
