itthaṁ bṛhad-vrata-dharastapaḥ-svādhyāya-saṁyamaiḥdadhyāv adhokṣajaṁ yogīdhvasta-kleśāntarātmanā
Translation:
In this way the devotional mystic Mārkaṇḍeya maintained rigid celibacy through penance, study of the Vedas and self-discipline. With his mind thus free of all disturbances, he turned it inward and meditated on the Supreme Personality of Godhead, who lies beyond the material senses.
