Actually, the sutra system also acknowledges the tantric view, just that it was not emphasized by the Buddha in his teachings to people of lesser capacity. In some texts, sutra assents tacitly to this view, claiming that when bodhisattvas attain the eighth bhumi, three transformations or three pure states take place. One of the pure states is purity of the five sense organs. When the five sense organs are purified, we see all things, including this world we are living in, as sublime as the Western Pure Land of Amitabha or the Eastern Pure Land of the Medicine Buddha. The Buddha told us in fact this world has always been this way, and has never changed. Because ordinary people have afflictive and cognitive hindrances, the true reality of the world is thus obscured. Upon reaching the eighth bhumi and having the five sense organs purified, only then will we see reality as it is. So, what is that reality? It is the mandala of the buddha, says Vajrayana. The Buddha expounded this clearly in many sutras, such as in the teaching of the Vimalakīrti Sūtra on dependent arising.
