The small part that reaches your conscious level, is a human characteristic.
What makes you an individual is the particular set of patterns that you hold in your mind, which have formed over your lifetime.
These characteristics determine your thoughts, behavior, and emotions, and influence your happiness, health, and success.
We all have the ability to change many of the characteristics which do not serve us well and replace them with better ones, but the process is not always easy.
Your mind is not just in your brain but the body and mind form an integrated information network.
