He felt sorry that he had not worshipped such a fine Goddess earlier and one of his eyes winked. Goddess Parvathi was angry that Kubera was seeing her with evil intention. She made his eye burst. Kubera lost one eye sight. Lord Kubera requested siva to forgive him and pleaded that he had not seen the Goddess with any evil intention. Siva asked Goddess to decide. Goddess Parvathi forgave Kubera and let one of the eyes grow on smaller size. So one eye of kubera is smaller than the other. Kubera was rewarded by shiva with the post of one of the Guards of eight disas. Kubera was given the post of guarding northen direction. Goddess made him the Lord of wealth and materials.
