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.
(5) CHARGING WATER.
Water may be charged with prana, by breathing rhythmically, and holding the glass of water by the bottom, in the left hand, and then gathering the fingers of the right hand together and shaking them gently over the water, as if you were shaking drops of water off of your finger tips into the glass.

The mental image of the prana being passed into the water must also be held.

Water thus charged is found stimulating to weak or sick persons, particularly if a healing thought accompanies the mental image of the transfer of the prana.

The caution given in the last exercise applies also to this one, although the danger exists only in a greatly lessened degree.
(6) ACQUIRING MENTAL QUALITIES.
Not only can the body be controlled by the mind under direction of the will, but the mind itself can be trained and cultivated by the exercise of the controlling will.
