The Vishnu Shankh also known as Ardha Chandra Shankh is a rare Tantric conch shell the worship of which, is said to give the worshipper the same benefits as that of worshipping Laxmi-Narayana.  In this post, I have described a special Mantra Sadhana to energize and purify the Vishnu Shankh for use in the home or office. Apart from the physical, mental, material and monetary benefits, I have also written about a couple beauty and health remedies, which can be practice using the Vishnu Shankh.
