Prana is the Sanskrit word for “life force energy." In Hindu philosophy including yoga, Indian medicine, and martial arts, the term refers collectively to all cosmic energy that permeates the universe on all levels. “Chi" (Chinese) or “Ki" (Japanese) are other words that also describe life force energy. 

Integral aspects of reflexology are the circle of energy between client and reflexologist, and the practitioner’s connection to life force energy.

Perhaps Gandhi explained it best:

“There is an indefinable, mysterious power that pervades everything…while everything around me is ever-changing, ever-dying, there is an indefinable living power that is changeless, that holds all together, that creates, dissolves and recreates.”
