abhyāsena nihanti mṛtyupalitaṃ kāmeśvaro vatsarāt sarveṣāṃ hitakārako nigaditaḥ śrīvaidyanāthena yaḥ /
vṛddhānāṃ madanodayodayakaraḥ prauḍhāṅganāsaṅgame siṃho'yaṃ samadṛṣṭiḥ pratyayakaro bhūpaiḥ sadā sevyatām //

through regular practice Kāmeśvara destroys death and grey hair within a year; / it has been proclaimed by the venerable Vaidyanātha as beneficial to all; / it causes the arising of the dawn of passion in the elderly, and in intercourse with experienced women / it is a lion of steady gaze that inspires confidence; let it always be used by kings.
