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.
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.
