Nei-Chia Tao-Sheng means the inner way to peaceful development by using the power of the Yi (mind).
One of the first principles in the study of Nei Chia is learning how to calm one’s mind. It is a “meditation
by movement” art form. The meditation is the inward motivation and the movement is the outward
expression.
If one learns how to relax and totally control the body to be responsive to minute stimuli (this acute sensitivity is known as “Shu” ), then one can use the will or mind, rather than the physical power to move the body with good co-ordination. The result of this will be a central nervous system, which will function calmly and harmoniously - thus a “meditation by movement”.
The Nei-Chia Tao-Sheng is based on the principles and theories from Japanese Zen Buddhism, Chinese Chan Buddhism Hindu, Hindu Mysticism and the highly developed exercises from the Tibetan yoga, Taoism and Hatha yoga and was extended and developed from these by Pro J. A. Holt. Therefore, the system is not the traditional Tai-Chi or Tai-Chia-Ma style or Wu style. It is simply Pro J. A. Holts personal style Nei-Chia, which is a development emanating from all these other systems.
The thumbs indirectly inhibit sensory stimulation of the eight cranial nerve. This is the purely sensory acoustic nerve.
The fifth cranial nerve, the trigeminal, is the primary nerve affected by pressure of the fingers in "Yoni Mudra". The trigeminal is the largest
cerebral nerve. The trigeminal divides into three major branches: the ophthalmic (sensory), the maxillary (sensory), and the mandibular,
one branch of which is sensory.
During the performance of Yoni Mudra the first finger touches over the infraorbital nerve. The ring-fingers press upon the superior
labial rami of the infraorbital nerve. The little fingers affect the inferior
labial branch of the mandibular nerve (sensory branch). (N.B The nerves pressed by the fingers are tactile.)
Indirectly the second cranial nerve, the optic, is affected by the closure or the eyes and thus
a fifty percent saving of body energy is brought about.
Ther mind is brought to a point of relaxed absorption within itself. "Pratyahara" or sense withdrawal ensues.
