This is an Aghori Mantra Sadhana and only very experienced practitioners of Indian Occult Sciences should attempt to perform this Mantra Experiment as there are strong chances that the practitioner might himself get killed by the Vampire.
The experiment should be conducted in an isolated Shivalaya where there are no chances of being disturbed while performing the Mantra Sadhana.
The practitioner should procure a Bone of a dead man from a Smashan Bhoomi and keep it under his sitting mat and then chant the Pishacha invoking Mantra 5000 times using a Rudraksha Japa Mala. Before commencing the Mantra Sadhana, the practitioner should offer a Bhog of Meat and Country Liquor [ Deshi Daru] to the Pishacha.
