In plain words
Because the Self is self-luminous by nature and free from any obstacle, true knowledge of the Self arises right within oneself without a shadow of doubt.
Close to the Sanskrit
Because of being devoid of obstacles and of the Self whose nature is direct experience itself, valid knowledge certainly arises there in one's own Self alone; there is no doubt.
