evam tam rucirapangim
drstva tasyam manas cakre
visajjantyam bhavah kila
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Thus Lord Siva saw the woman, every part of whose body was beautifully formed, and the beautiful woman also looked at him. Therefore, thinking that She was attracted to him, Lord Siva became very much attracted to Her.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Lord Siva was observing every part of the woman’s body, and She was also glancing at him with restless eyes. Thus Siva thought that She was also attracted to him, and now he wanted to touch Her.
