This Sadhana does not need Siddhi. The Sadhak has to take some very small stones [fine gravel] hold them in the right hand and then bind the gravel by chanting the mantra 108 times.
Then he has to without being noticed secretly throw the infused gravel on the body of the enemy whom he wishes to suppress. This Sadhana is said to completely remove any trouble from that particular enemy.
