Dual cultivation (性命雙修) is an important, if not the most important, concept in Taoist meditation (Taoist yoga, or Neidan). The concept is complex because Dual cultivation can be (and has been) applied to different areas as taught by the Masters over the ages. It is based on Tao Te Ching’s Tao concept of combining opposites into an integrated whole, since opposites have different manifestations and so has the resultant wholes. It is further complicated by the possibility, and indeed necessity, of having endless upgrades of one "wholeness" to the next level of "wholeness".
In Tao Te Ching, the key dual cultivation is morality versus inner spiritual-chi practice. The process (as with other manifestation of dual practice) is always like this, schematically:
Morality1 – Spirituality1 – Wholeness1 – Morality2 – Spiritual2 – Wholeness2 ….etc.
Another key dual practice manifestation is personal development versus good ruler behaviour, again schematically it is like this:
Personal1 – Society1 – Wholeness1 – Personal1 – Society2 – Wholeness2…..etc,
In Hui Ming Jing, the key dual cultivation (focusing on Spirituality practice) is Wisdom (consciousness) versus Chi (unconscious impulses).
Schematically, it is like this:
Wisdom1– Chi1– Wholeness1 – Wisdom2 – Chi2 – Wholeness 2,…..etc.
Another key dual practice manifestation is Mind versus Body, again schematically it is like this:
Mind1 – Body1 – Wholeness1 – Mind2 – Body2 – Wholeness2,……etc.
Dual Practice is Tao-in-practice Par Excellence, and can be applied creatively in daily lives, by people who understand Tao.
