Some saints, like Sakyamuni, Lao Tzi, Zhuang Tzi, and so forth, could, in a very snatch, reduce the space separating the two above-said regions, although they are very far away from each other, from the viewpoint of existence. The boundless sea of Lower Elixir Field exists like a handful of water, pure, limpid and clear. It is a great blessing descending upon the man who can recognize it and advances toward it despite all formidable difficulties. Because general description gives it a meaning in part concerning emotions rather than exploring its original formation that is free from the contamination of desires and emotions. At the very instant of Great Transformation, and before the myriad of things acquire respective shapes, man's congenital nature is pure and virginal.
Nothing exists to interfere with it and nothing to induce it to take diverging path.
With no origin to explore, with no end to divine, man's congenital nature exists primitively. After the annihilation of all things this survives, and before the existence of all things this first came into being. No great thinker could possibly guess where it is, because it exists beyond range of man's thinking ability, and in what form it presents itself, for it lies beyond the range of the time and space. Wearing away all thoughts you could not detect its existence, meanwhile driving all ideas to all quarters of reasoning realm you could not catch sight of its shape. Also, no circumference exists to mark out it, and no interior and exterior to form it.
