Words have profound suggestive power, and there is healing in the very saying of them. Utter a series of panicky words and your mind will immediately go into a mild state of nervousness. You will perhaps feel a sinking in the pit of your stomach that will affect your entire physical mechanism. If, on the contrary, you speak peaceful, quieting words, you mind will react in a peaceful manner.
Use such a word as “tranquility.” Repeat that word slowly several times. Tranquility is one of the most beautiful and melodic of all English words, and the mere saying of it tends to induce a tranquil state.
Another healing word is “serenity.” Picturize serenity as you say it. Repeat it slowly and in the mood of which the word is a symbol. Words such as these have a healing potency when used in this manner.
It is also helpful to use lines from poetry or passages from the Scriptures. The words of the Bible have a particularly strong therapeutic value. Drop them into your mind, allowing them to “dissolve” in consciousness, and they will spread a healing balm over your entire mental structure. This is one of the simplest processes to perform and also one of the most effective in attaining peace of mind.
