I came across this pooja in this website ...
http://www.starsai.com/starsai-shradha-saburi-pooja/. This is a very simple pooja that we can do everyday and show our love and devotion to baba. You can do it for 9 days or 50 days in case you have a specific problem.
You have to light 2 lamps before baba, pray him and read atleast 1 paragraph of Saisathcharitha , then chant sai sai for 10 mins and tell sai all your problems. Finally offer whatever you can to baba.
I wanted to share it in this forum for people who do not knopw about it. Please visit the website for a detailed description...
Jai sai ram....
