PURPORT
Lord Siva cannot be victimized by maya. Therefore it is to be understood that Lord Siva was being thus harassed by Lord Visnu's internal potency. Lord Visnu can perform many wonderful activities through His various potencies.
parasya saktir vividhaiva sruyate
svabhaviki jnana-bala-kriya ca
(Svetasvatara Upanisad 6.8)
The Supreme Lord has various potencies, by which He can act very efficiently. To do anything expertly, He doesn't even need to contemplate. Since Lord Siva was being harassed by the woman, it is to be understood that this was being done not by a woman but by Lord Visnu Himself.
