In the Skanda Purana, Parvati requests Shiva to allow her to reside with him, embracing limb-to-limb, and so Ardhanarishvara is formed. It also tells that when the demon Andhaka wanted to seize Parvati and make her his wife, Vishnu rescued her and brought her to his abode. When the demon followed her there, Parvati revealed her Ardhanarishvara form to him. Seeing the half-male, half-female form, the demon lost interest in her and left. Vishnu was amazed to see this form and saw himself in the female part of the form.
