Jai Sri Ganesha,
It is last last Saturday of the Saturn in its retrograde phase.
Which started with Utpaat Yoga on 11th May and going to last till 29th Sept,
Saturn is changing phase from retrograde to direct in the evening of Bhom Pradosh, though in shadow of Mrityu Yoga yet with gracious truth of auspicious Pradosh, a define day of Lord Shiva,
Last Saturday of retrograde truth of Saturn in Purushotam Maas may help devotees on path of truth and submission, here Saturn may distribute the fruits for eternal gains to devotees and submissive followers,
May Lord Bless all,
Thanks please
