Powerful Black Magic Reverse Vishnu and Krishna Mantra

In this post, I have written about a potent and fast-working Mantra that can be dedicated to either Bhagwan Vishnu or his Eighth Avatar, Shri Krishna, to instantly eliminate any kind of Black-magic spells and Negative Energies. This is a tried and tested Mooth Nashak or Black-magic Reversing Mantra that can reverse the spell back to the spell caster who has cast it on the practitioner.
