हाथ खडग मूशल लें, कमला गरुड़ पाय परति आवै | ताहि मारि हो नरसिंह वीर व्रामु | नरसिहं वीर की प्रचाणु शक्ति लै लै लै लै त्रिशुला उत्तमूला गाजी जाई छढाउ ताही छाडि |

The conclusion of this Mantra Experiment is said to influence the mind of the enemy and weave a Web of Mayajaal around him and misguide him so that he does not harm the practitioner and disappears from his life.
