Namah Shivaya,
Namaskarangals to all,
I want guidance to know the procedure,like if someone can share any sankalpa mantram before doing giri pradakshinam on a pournami day and the best time to do it on a pournami day,like if it is preferred to start in the night or during the day.I have done giri pradakshinam and visited arunachala 12 years back when I was 17 years old.
Regards,
