As stated in the Brahma-samhita (5.40), yasya prabha prabhavato jagad-anda-koti-kotisv asesa-vasudhadi-vibhuti-bhinnam. There are various planets and various atmospheres within this universe. The atmosphere of the heavenly planet from which Urvasi descended after being cursed by Mitra and Varuna was different from the atmosphere of this earth. Indeed, the inhabitants of the heavenly planets are certainly far superior to the inhabitants of earth. Nonetheless, Urvasi agreed to remain the consort of Pururava, although she belonged to a superior community. A woman who finds a man with superior qualities may accept such a man as her husband. Similarly, if a man finds a woman who is from an inferior family but who has good qualities, he can accept such a brilliant wife, as advised by Sri Canakya Pandita (stri-ratnam duskulad api). The combination of male and female is worthwhile if the qualities of both are on an equal level.
