Translation
The yogī should then meditate on the chest of the Supreme Personality of Godhead, the abode of goddess Mahā-Lakṣmī. The Lord's chest is the source of all transcendental pleasure for the mind and full satisfaction for the eyes. The yogī should then imprint on his mind the neck of the Personality of Godhead, who is adored by the entire universe. The neck of the Lord serves to enhance the beauty of the Kaustubha gem, which hangs on His chest.
