Paul Brunton Philosophic Foundation homepage > Notebooks of Paul Brunton
If the aspirant will take care to fill his mind with thoughts that are always elevating, always positive, and always constructive; if he will be vigilant to keep out all thoughts that are degrading and destructive, this simple technique will keep his mind so continuously filled with the right kind of thought and feeling that he will unconsciously and little by little completely overcome the wrong kind. Thus his character will change and approach his ideals.
