Change is inevitable. Our bodies change constantly. The weather changes. The planet itself is always changing.
Human beings can execute behaviors, based on thought, which can change our environment. Yet, how do we use this exceptional ability? We use it to accumulate things at the expense of our health and well being.
The change which some politicians are promoting in their speeches is not really change for the betterment of the species or the planet. Their focus is to preserve the bad habits of materialism and selfishness which are rapidly degrading the planet. They are obsessed with human creations, wealth and power.
True change for the better would be focused on education, the alleviation of poverty by taxing the materialistic, directly dealing with overpopulation and holding responsible those who have plundered human wealth for irresponsible and destructive purposes. However, the domination of world governments by the very greedy corporate entities who have been destroying the planet for decades has perhaps already doomed the human species to a bleak future for some time to come.
Individual practice always allows for positive change in one human life. If the current destructive course of the human experience is to be reversed, individual practice will be at the core of that change. Living in the light of truth with compassion and responsibility is one way to create daily changes in the world, one life at a time.
