A man can make a thought-form intentionally, and aim it at another with the object of helping him.

This is one of the lines of activity adopted by those who desire to serve humanity.

A steady stream of powerful thought directed intelligently upon another person may be of the greatest assistance to him.

A strong thought-form may be a real guardian angel, and protect its object from impurity, from irritability or from fear.
An interesting branch of the subject is the study of the various shapes and colours taken by thought-forms of different kinds.

The colours indicate the nature of the thought, and are in agreement with those which we have already described as existing in the bodies.
