Jai sri Ganesha,
Sri Purnima Shradd today, this is better placed optimized Purnima with respective span to oblige man to perform suitable oblations in truth with Shradd,
This Pitar Paksh is elongated by span started with Shool/musal Yoga yet have many favorable chapters for man to enjoin truth of life,
Sri Pitar Puja is the prime subject of the Paksha, Brahmans are taken as presiding deity to perform oblations to redirect suitable,
Sri Brahman Puja is subject of the day which may act as carrier to help souls of ancestors there in that region in the form of their need,
May Lord bless all,
Thanks please
