spiritual practices

Neidan (inner elixir) aims to stabilize prāṇa (प्राण) along the midline. Whereas neigong practice largely engages flows of qi in the body to begin the process of collecting energy in the central channel, neidan now takes free flight and courses through inner worlds powered almost exclusively via the mind itself (a more subtle version of qi or prāṇa).

Here's a typical sādhana (set of spiritual practices) at the beginning stage of neidan cultivation: 


phowa — tying the midline into near space

The References page has some great suggestions for teachers and more advanced practices such as combining mantra with neigong along both midline and off-midline meridians; and, phowa—a Tibetan Buddhist practice that sends energy up the midline and out the crown of the head into near space to merge with a visualized deity.
