Whenever there appears to be a ‘good’ behavioral rule or principle or law, there is always a much more expansive spiritual principle or spiritual law behind it.

Even though religions have as their early foundation a collection of spiritual principles, these have most often been obscured by layers of behavior principles that have been superimposed as rules or laws.

As an example, since we occupy bodies, fitness of the body currently is a social priority. Schools have developed Physical Education programs to ensure some form of exercise for each student, and there are usually many forms to choose from, throughout the school year.

But if the student lives on a farm, there might be activity that more than fulfills the requirement without a formal Physical Education program.

The Spiritual principle behind the behavior rule for fitness has to do with purifying the total being, including reasonable physical fitness and all its choices, including emotional and feeling fitness, including the development of discipline (in itself a spiritual principle) that is able to be generalized to any area of life, including the fitness of awareness of the chain of cause and effect put in motion by each choice of  behavior, indeed, each choice of thought.

Thought generates feelings or emotions, which may generate attitudes, which may generate belief systems, which THEN generate behavior. This works whether the thoughts are allowed in the negative or in the positive.

The mind then, which is a Spiritual Principle function (as opposed to the brain, which is mostly behavioral), may allow the most fit thoughts, which produce the most joyful feelings, which produce the most balanced attitudes, which produce the most flexible belief systems, which allows for the most productive behavior.
