SB 6.3.9
niyamanam tavadesad
asmabhir yatana-grhan
vyamocayan patakinam
chittva pasan prasahya te
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
We were bringing the most sinful Ajamila toward the hellish planets, following your order, when those beautiful persons from Siddhaloka forcibly cut the knots of the ropes with which we were arresting him.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Srila Visvanatha Cakravarti Thakura remarks that the Yamadutas wanted to bring the Visnudutas before Yamaraja. If Yamaraja could then have punished the Visnudutas, the Yamadutas would have been satisfied.
