The Siddhi is gained by visiting a Smashan Bhoomi at 11 O’clock at night and sitting on the chest of a dead body and chanting the Karna Pishachini Aghori Mantra.
The Karna Pishachini Mantra for having the future whispered into the ear by the Karna Pishachini Yakshini should be chanted 100,000 times in as short a period of time as possible.
The Sadhaka should chant the Mantra continuously taking only short breaks for essential chores. Until the Karna Pishachini Mantra Prayoga has concluded, the Sadhaka should not have a bath, shave or brush his teeth. The Sadhaka should use a Rudraksha Beads Japa Mala for counting the number of Mantra Chants.
After, concluding the Mantra Experiment, if the Sadhaka is successful in his quest to invoke the Karna Pishachini Yakshini, she will whisper the future in his ear whenever he needs to know the future destiny of some person.
