Nang Jang (refinement of perception) is the name given to a visionary text of the Tibetan
Dzogchen tradition, in which the Dzogchen master, Dudjom Lingpa, experiences visionary visitation from fourteen awakened beings, including
Avalokiteshvara and
Longchenpa, who teach him of the illusory nature of all things and how they arise from
the basis or primordial state. According to the teachings bestowed upon Dudjom Lingpa by the highly advanced spiritual beings who visit him in this text, all phenomenal, sensible things are empty and illusory. Yet there is that which is not separate from them, nor they from it, and which can be described as the 'ground of being'. Orgyan Tsokyey Dorje (one of the spiritual visitants) states: The text also tells of how the
Buddha nature, the heart of awareness, is utterly pure and lucid and constitutes the very life essence of all things, both samsaric and nirvanic. Ekajati declares: This is ultimate reality, a state of truth beyond ordinary mundane consciousness and beyond the power of words to describe. It is designated by Zurchhung Sheyrab Dragpa in the text as "a supreme and inexpressible state", the "fundamental nature beyond ordinary consciousness." The practitioner of this spiritual path is urged to strive for obtaining of an ultimate all-knowingness which transcends time: ==References==
