Like psychoanalysis, Buddhism is shot through with various interpretations of dreams. The Yogacara studies of the phenomenological Buddhism regard the dream as a type of conscious activity. Another interpretation is that the dream is independent of reality and can serve to be an equivalent of dharma, an interpretation illuminated in the well-known passage of the Diamond Sutra: "Only this can be the way of perception. All this fleeting world is a star at dawn, a bubble in a stream; a flash of lightning in a summer cloud, a flickering lamp, a phantom, and a dream." Thus the dream is one of the dharmas that enables the practitioners to attain to sunyata through a realization of the never-ending change in all realities. In addition to these examples, the practice of the "dreaming soul" can be seen in the Tibetan Buddhism. With its rich and long-established interpretative traditions in Buddhism, therefore, the dream calls for a deeper and broader exploration of its miscellaneous manifestations. In this regard the achievement of A Summary of Yunshanmengyu is worth noting, a section from Caoxiyidi written by the Chan savant Cheyongzhouli in the late Ming dynasty. Circling round the "dreaming enlightenment," this four-chapter section explicates the mystery of life and provides practitioners with a springboard to satori. To re-emphasize the role of dreams as a way of Buddhist practice, several karma stories are added at the end of this section.
