Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The goddess of fortune, Laksmi, the dust of whose feet is worn on the head by others, waits upon You, as appointed, for she is anxious to secure a place in the abode of the king of bees, who hovers on the fresh wreath of tulasi leaves offered at Your feet by some blessed devotee.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As previously described, tulasi has attained all superior qualities due to being placed at the lotus feet of the Lord. The comparison made here is very nice. As the king of bees hovers over the tulasi leaves offered to the lotus feet of the Lord, so Laksmi, the goddess who is sought by the demigods, brahmanas, Vaisnavas and everyone else, always engages in rendering service to the lotus feet of the Lord. The conclusion is that no one can be the benefactor of the Lord; everyone is actually the servant of the servant of the Lord.
