Tharpanam

[Nagarajan Subramania]

We are following darba stampam. Since we are living in outskirt of pune, vadyars availability on amavasya day is very remote.
Therefore, I am doing it reading from the book. Since we are following darba stampam, what changes in mantras have to be
made in sankalpam. Please explain in detail. Since I can follow sanskrit if it is given in sanskrit it will be useful.
