A Way to Build Self-Confidence
By Sri Harold Klemp
If you should have your real strength of character affected by a lack of self-confidence, use this technique to build yourself up again.
First find the spots in your aura or personal atmosphere that are self-conscious, shy, timid, or overly sensitive. These tend to attract people who impose upon your weakness. With a mental command, ask those people to move out of your way. Mentally demand respectful attention.
Next build up the opposite qualities of mind and character to replace these self-conscious qualities. Fill yourself with positive courage so that the positive force you generate can actually be felt when you pass through a room.
Adopt the mental attitude and personal atmosphere of a person with great confidence. Always be direct and positive in your approach to all things. Put all your spiritual force behind your smile, your replies, and your thoughts.
