Wherever the word comes from (I don't know, but sounds Indian), it's not an English word, so I suppose you're allowed to use the word in Arabic as well.

Prana Energy

Introduction
Prana is an auto-energizing force which creates a magnetic field in the form of the Universe and plays with it, both to maintain, and to destroy for further creation. It permeates each individual as well as the Universe at all levels. It acts as physical energy, mental energy, where the mind gathers information; and as intellectual energy, where information is examined and filtered. Prana also acts as sexual energy, spiritual energy and cosmic energy. All that vibrates in this Universe is prana: heat, light, gravity, magnetism, vigor, power, vitality, electricity, life and spirit are all forms of prana. It is the cosmic personality, potent in all beings and non-beings. It is the prime mover of all activity. It is the wealth of life.
