SB 9.3.6
apy abhadram na yusmabhir
bhargavasya vicestitam
vyaktam kenapi nas tasya
krtam asrama-dusanam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
How strange it is that one of us has attempted to do something wrong to Cyavana Muni, the son of Bhrgu. It certainly appears that someone among us has polluted this asrama.
