Update: Just today, I recorded the song for this. Please ignore some mistakes I made. It is a song for almost 19 minutes, so there was no time to record the same more than once. It is recorded just for your reference. I have recorded exactly like my Mom sings, Thanks MOM.
This is called Sampat Shukravarada Haadu. It has to be sung after performing Lakshmi Pooja in the evening on 5 Friday’s during Shravana Masa.
The book I had is in Kannada, and was given to me by my Mom. It is very old. Some of the pages came out a little blur. Forgive me for that. It has 26 pages and 119 paragraphs.
You can listen to the song online here. Link provided by Rashmi.
