Jai Sri Ganesha,
First Monday or moon day of the Sacred Saawan that on Si Purna Tithi is a meritorious chapter to enjoin in spirit with,
This sacred Saawan will have four Mondays to gratify self in truth with oblations in the lotus feet of Lord Shiva,
Four Mondays, Two Pradosh, and One Shivratri will oblige life in varying forms, devotees may encash this truth of eternity,
There is nothing parallel to offering the Ganga Jal on Shiv Lingam, Offering Bel Patra will be an additional truth in oblations of the day,
May Lord bless all,
Thanks, please
