Accepting the present does not mean to be idle and inactive. By being inactive you are actually resisting the present. Meditation can help you release resistance, but the act of sitting down, doing nothing and quieting your mind does not automatically mean you are not resisting.
If you are currently looking for happiness in your life you won’t find it. Happiness does not lie outside of yourself, so you can’t look for it. Understand that the physical form of this world is constantly changing, you can’t really hold on to something. It’s like trying to put label called “Happy” on a rock. But what if you lose the rock? Will you be forever unhappy?
You have to fully love and accept your current situation, because that is what there will always be. When you find true love and happiness in the present then you can fully appreciate everything this universe has to offer. When you are able to accept everything this world throws at you, you will receive everything you will ever need to be eternally happy.
