Jai Sri Ganesha,
Sri Pradosh today in conjunct with Shivratri, Both events belong to the truth of Lord Shiva,
The first event is pitched at Pradosh Kaal and the other at Kaal Ratri, both are meant to yield favors for devotees,
Pradosh Kaal is usually taken at the threshold of sunset, which leads truth to the dark insight to visualize the truth in truth with cause,
And Lord Shiva is a tangible help on the path whether it is for day-to-day sustenance of self in the journey or in the cult of self eternally,
May Lord bless all,
Thanks, please
