... it seems to me that dzogchen practices are centered on re-integration into the formless tao, through sublimation of the elements into their non-reactive nature ( non causal-effect related ); in essence the nullification of them operating under either awareness or ignorance ( positive or negative ) to their roots in the absolute (the tao/khunzi).
Taoist practices vary widely. What seems is being discussed here is the actual opposite of dzogchen aims. Taoist practice to transform their physical bodies into pure yang energy ( all positive ). This practice is similar to cultivating an astral body or pure light.
... if you have ever seriously meditated and opened your heart, you will know what this light or energy is. It is pristine. Beyond words. Diamond like, because it feels like a smooth sparkling stream that is absolute and indestructible.
