Inner alchemy, 8 chapter, Great Stillness, p.202,203:

The goal of internal alchemy … cannot even be attempted while people are focused on the need to feel good about what is inside themselves.

… traditional practice is to initially take all the blockages in your first six energy bodies and release them in much the same sequence as the dissolving methods of the water school. The fire method, however, accomplishes this by creating tremendous physical heat in the lower tantien. The purpose of this heat is to incinerate your bound internal blockages. (This process can take a long time, just as the fundamental dissolving methods can.)
As the bulk of the gross traumas, attachments, and so on, are being cleared out, the heat in the lower tantien becomes extremely fierce—enough to cause profuse sweating.
Eventually, burned-off gross matter naturally turns into a ball of light and drops down into the perineum, just as, in the water method of meditation, the encrusted material dissolves, leaving only the unadorned gem.
From here, the process of internal alchemy called nei dan begins. The ball of light commences to circulate throughout the microcosmic orbit. There are specific alchemical procedures for each place where the ball arrives.
Gradually, the ball of light links all the energy centers and channels in the body, transmuting them into Consciousness, which then begins to expand, body by body, until it encompasses the whole of the universe.

do this without having first released the encrusted material around Consciousness itself… blithe
