saksat-krtam me paribarhanam hi
vina puman yena maha-vimohat
krtanta-pasan na vimoktum iset
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The true activity of the sense organs — mind, sight, words and all the knowledge-gathering and working senses — is to engage fully in My service. Unless his senses are thus engaged, a living entity cannot think of getting out of the great entanglement of material existence, which is exactly like Yamaraja’s stringent rope.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As stated in the Narada-pañcaratra:
sevanam bhaktir ucyate
This is the conclusion of bhakti. All the time, Lord Rsabhadeva has been stressing devotional service, and now He is concluding by saying that all the senses should be engaged in the Lord’s service. There are five senses by which we gather knowledge and five senses with which we work. These ten senses and the mind should be fully engaged in the Lord’s service. Without engaging them in this way, one cannot get out of the clutches of maya.
