Rambha in mythology is the Queen of the Apsarase, the magical and beautiful female beings in Devaloka (heaven).
She is unrivalled in her accomplishments in the arts of dancing, music and love-making. She is often asked by the king of the Devas, Indra to break the Tapasya (meditation) of sages so that the purity of their penance is tested against temptation, and also that the order of the three worlds remains undisturbed by any one man’s mystical powers. When she tries to disturb the penance of sage Vishwamitra, she is cursed by him to become a rock for 10,000 years till a Brahmin delivers her from the curse.
In the epic Ramayana, Rambha is raped by Lord Ravana, king of Lanka, who is thereby cursed by Lord Brahma that if he violates another woman again, his head will burst. This curse protects the chastity of Sita, the wife of Lord Ram when she is kidnapped by Lord Ravana.
