Prana is the universal principle of energy or force. It is a vital, all pervading force. It may be either in a static or dynamic state. It is found in all forms, from the highest to the lowest, from the ant to the elephant, from the unicellular amoeba to man, from the elementary form of plant life to the developed of animal life. Prana is force on every plane of being, from the highest to the lowest. Whatever moves or works or has life is but an expression or manifestation of Prana. It is Prana that shines in your eyes. It is through the power of Prana that the ears hear, the eyes see, the skin feels, the tongue tastes, the nose smells and the brain and the intellect perform their functions. The smile of a young lady, the melody in music, the power in the emphatic words of an orator, the charm in the speech of one’s beloved, are all due to Prana. Fire burns and the wind blows through Prana. Rivers flow and planes move in the air through Prana. The steam engines work and trains and cars move through Prana. Radio waves travel through Prana. Prana is electron, force, magnetism and electricity. It is Prana that pumps the blood from the heart to the arteries or blood vessels. Prana does digestion, excretion and secretion. It is expended in thinking, willing, acting, moving, talking and writing. A healthy, strong man has an abundance of Prana or nerve-force or vitality. It is supplied by food, water, air, solar energy, etc. The supply of Prana is taken up by the nervous system. It is absorbed in the process of breathing. The excess is stored in the brain and nerve centers. When the seminal energy is sublimated or transformed, it supplies an abundance of Prana to the system. It is stored up in the brain in the form of spiritual energy.
