Sandhyavandanam,Puja or a Japa always generally begins with a Sankalpa.
I've found the following two Sankalpa Mantras on web.
"Mamopatha Samastha, duritha kshaya dwara, Shri Parameswara preethyartham...
Mamo partha samastha durithakshaya dwara , Sri Parameshwara preethyartham...
I have not given the complete mantras as it is not needed for my purpose.
As can be seen the mantras differ only by a word patta/partha.
My question-Which one of the two mantras is the correct one?
Another allied question-What are the meanings of the words "patta" and "partha"?
