The Hindu-Yogi Science of Breath

If some friend is deficient in vitality you may aid him by sitting in front of him, your toes touching his, and his hands in yours. Then both breathe rhythmically, you forming the mental image of sending prana into his system, and he holding the mental image of receiving the prana. Persons of weak vitality or passive will should be careful with whom they try this experiment, as the prana of a person of evil desires will be colored with the thoughts of that person, and may give him a temporary influence over the weaker person. The latter, however, may easily remove such influence by closing the circuit (as before mentioned) and breathing a few rhythmic breaths, closing with the Cleansing Breath.
