prayasah prakrtas capi
striyam rahasi bibhrati
bibharti sadasi striyam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Ordinary conditioned persons generally embrace their wives and enjoy their company in solitary places. How wonderful it is that Lord Mahadeva, although a great master of austerity, is embracing his wife openly in the midst of an assembly of great saints.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The word maha-vrata-dharah indicates a brahmacari who has never fallen down. Lord Siva is counted among the best of yogis, yet he embraced his wife in the midst of great saintly persons. Citraketu appreciated how great Lord Siva was to be unaffected even in that situation. Therefore Citraketu was not an offender; he merely expressed his wonder.
