According to Pararaton and local tradition, Ken Arok's usurpation of Tunggul Ametung was caused by Ken Dedes' exceptional beauty and charisma. The story is that Ken Arok was standing close near the royal carriage as it halted and caught a glimpse of the young queen. When her clothes accidentally parted, Ken Arok caught sight of her naked legs and thighs and he saw that her genitals were 'shining'. A Brahmin, Lohgawe, told Ken Arok that this radiance was the sign that Ken Dedes bears the divine quality and would be the bearer of kings. Her beauty was said to have been so perfect that whoever married her, regardless of his status, would inevitably be destined to become king of kings. By this, Ken Arok was motivated to dispatch Tunggul Ametung.
