“Don’t think that *prana* is an Eastern concept unknown to the western mind. The 18th Century romantic poet William Blake wrote:

Man has no Body distinct from the Soul!
for that called Body is a portion of Soul
discerned by the five Senses, 
the chief inlets of Soul in this age.
Energy is the only life and is from the Body;
and reason is the bound or outward
circumference of energy.
Energy is eternal delight.

the “energy” that Blake discovered to be eternal delight is not the energy that physicists talk about (the concept of energy did not enter physics until the 1830s), but is the *prana* of the Indian tradition and the Chi of the Chinese” Amit Goswami, PhD
