The Spiritual Body (Sanskrit: Shookshma Kaya) has its own, innate, Spiritual Shadow (Shookshma Chaya).
The Four marks the manifestation of source-and-life in time-and-space.
Meditation is a state of consolidation of inward energies.
Yoga, then, provides the outwardly 'release' of this energy into time-and-space.
The release that empowers here-and-now.
Release is as much fundamental as consolidation.
A perfect balance of life is unattainable otherwise.
For some, a more aggressive form of such a manifestation and release is required than simple Yoga.
There are many renowned practices catering to various denominations of such aspirants.
Below is an example of Tai Chi which is but only one such method among many.
Tai Chi is a method of 'release and capture' wherein, the inert energies thus consolidated at meditation are brought forward, manifested, dispersed and consolidated again but in physical formate this time, augmenting the physical 'being' (body) to a higher plane.
A Tai Chi master shall never falls sick,
A 'perfect' Tai Chi master shall perfect all ways of life-affecting elements,
Having thus mastered life-altering energies, the master shall transcend the interplay and overlap of energies between their physical and spiritual formates,
A Tai Chi master may thus aim to attain immortality,
A Tai Chi master may thus claim to attain Nirvana.
