What is change? The dictionary says this: to make the form, nature, content, future course, etc., of (something) different from what it is or from what it would be if left alone: to change one's name; to change one's opinion; to change the course of history. To transform or convert.
As we grow from infants, we constantly make small changes in our behavior to accommodate the changing world around us. As we grow older, we realize that we have a choice. We may think we know what is best for us, so we make decisions that are not what we expected. Maybe we regret what we did or made bad choices; that's okay, it is part of growing. There should be a time when we realize that we may want to change the way we think to make our life easier or more fulfilling. Let's figure out what how to do that.
This is from the Science Of Mind text.
"The most important thing that any student of the Truth can understand is the real meaning of self-existence. Whatever the nature of First Cause is, It must be Self-Existent, or else It could not be at all. It is, perhaps, hard to comprehend that there must be, and is, a Power which exists simply because It is what It Is; and yet this is the mainspring of all right metaphysical work and endeavor.
We must come to believe in, and trust, that Power of Life and Intelligence which is God, or First Cause. We must understand that we deal with First Cause whenever we think, at any, and at all, times. If we had to gather energy with which to energize the Creative Principle of Life, where should we go to get the energy with which to energize It?
We are constantly thrown back upon the fundamental proposition that Life already Is; and that we use a Power which already Is. Let us then, without doubt or fear, throw our word into that Great Receptivity and trust It to do the work."
I know you heard the term "do not live in the past, live in the present". This is true, although I will take it a step farther. What is change? It is the key to happiness. It is the ability to see, know and realize that every decision we make whether we are aware of it or understand it, it will affect us in what we call the future. This is cause and effect.
Try to really understand what I am going to say, please try to open your mind to all possibilities. There is no past, no present, no future, only now. As we think our next thought, anything before is the past. As soon as we realize this, the next thought is in the past and on it goes. We need to change our process of making decisions to positive habits. This will help in our future. Remember cause and effect; everything we do right this second will affect us in the next second. Leave nothing to fate, learn to make good decisions, make it a conscious effort so it becomes natural when you are not conscious of your thoughts in real time.
