How to do the Pitru Paksha puja at home

After the bath and before midday, facing south: water and black til for the pitars, each by name. Given every morning of the fortnight by those who keep it — in most houses the son whose father has died.

1. Morning

   The bath, and what to keep ready

   1. Bathe in the morning — in a river or a pond where there is one, at home where there is not.
   2. Put on a washed dhoti, white or pale yellow.
   3. Sit on a seat of kusha, facing east to begin.
   4. Keep within reach: a copper lota of water, a small copper plate to receive it, black til, a few grains of jau, a little raw milk, white flowers, tulsi and a few blades of kusha.
   

2. Morning

   Achaman

   1. Pour a little water from the lota into your right palm.
   2. Sip it once as you say each of the first three names — three sips in all.
   3. With the fourth name, pour a little water over your right hand to wash it.
