Psychologist teach us that there are two mental laws that contribute heavily to our mental state of being. In other words, whether we’re happy or sad. They are:

1: The Law of Concentration.
2: The Law of Substitution.

The Law of Concentration states that whatever we dwell upon grows in our life experience. Whatever we think about on a continual basis becomes a part of us. Yes, we become what we think, and the more we dwell on something, the more we have of it in our lives.

The Law of Substitution states that our conscience mind can only hold one thought at a time. It makes no difference to our mind whether the thought is “negative” or “positive,” it can only hold one at a time. However, we can choose to substitute “negative” thoughts with “positive” thoughts, thus changing our mental state of being. –Dr. Joel B. Santos
