The dictionary defines "happiness" as the qualities of stability, depth, and calmness. This type of happiness is neither intense nor temporary and exists more within our state of mind, not entirely dependent on external factors.

Research has shown that cortisol, a stress hormone in our bodies, can have negative effects on our moods, emotions, and memories.

MRI's and CAT scans have measured shrinkage of the hippocampus, the brain's center for learning and memory. The limbic system, of which the hippocampus is part, is particularly susceptible to stress, which ties in with moods and emotions.

Brain researchers tell us that when we're happy, the left pre-frontal cortex is electrically active. When we're fearful or depressed the right pre-frontal cortex is active.

Contemporary brain research is resulting in some startling scientific information. For example, contrary to previously held concepts, human beings are producing new brain cells daily, not only early in life, but well into the later years of life. The creation of new brain cells implies great promise for adaptability (personal change), optimization of function, and healing potential. It is an exciting time as science and mind/body health begin to merge.

Ancient meditative philosophies proposed that happiness as described earlier is achievable through discipline…training of the mind.

According to psychiatrist Howard Cutler, "…practices can be applied directly to our lives to simply help us become happier, stronger, perhaps less afraid."
