tad bhaktanam atmavatam sarvesam atmany atmada atmatayaiva.
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The Supreme Personality of Godhead, who is situated in everyone’s heart as the Supersoul, sells Himself to His devotees such as Narada Muni. In other words, the Lord gives pure love to such devotees and gives Himself to those who love Him purely. Great, self-realized mystic yogis such as the four Kumaras also derive great transcendental bliss from realizing the Supersoul within themselves.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The Lord became Bali Maharaja’s doorkeeper not because of his giving everything to the Lord, but because of his exalted position as a lover of the Lord.
