I feel there is huge power in that statement. I adopted it as my motto and favorite quote many years ago. I believe the thoughts words and actions from the proverbial yesterday are what we are living out today. So, take the time today, right now, to have good thoughts, use pleasing words, take right action in the present moment, and feel grateful for everything. Once you get this process started and practice it everyday, it will become a new , and good, habit. Soon your tomorrows will be wonderful and you will be looking back at your yesterdays in amazement.
This is not to say that you will never experience sadness again. How can you ever truly know joy if you have nothing to compare it to? This contrast in experiences is what causes us to use our free will to make choices of what we prefer. What a wonderful gift we all have, the power of choice. Choosing our feeling and experiences is how we continue to grow and change.
Most people are not aware of the power they were born with. They are stuck in a cycle of thoughts and feelings and do not realize how easily they could break out of it. It is just a matter of making a conscious choice to change their thoughts and soon everything else will follow. Humans are the only creatures on this lovely blue planet who can be this conscious of the power of choices and the consequences of making them.
Consequence is a word that tends to have negative connotations attached to it, but it can be a good thing. Consequence is just the outcome of a choice, the relationship of cause and effect. Make a good choice and you will have a positive consequence.
