This Prayog has to be conducted after sunset on any Thursday in front of a Mazar [grave] or a Dargah [shrine constructed over a grave].
The practitioner has to offer some sweet food item and Attar [perfumes, normally found in small near a Mosque] to the Mazar.
Then he has to chant the Ayat given above 11,000 times, using a Haquik Mala [a counting rosary made from Agate]. This ensures Mastery over the mantra.
Then whenever the practitioner experiences fear and dread, he has to chant the Ayat 99 times. This can be done anywhere, even if he is on a journey or in a dangerous place.
