When we come into this world we come in as a completely open trusting souls. We are then taught to "trust" and believe our parents, friends, authority figures, church etc. Especially in some of us older folks generation, we were taught to do this unconditionally.
Many bought into the fairy tell. Many of us have suffered deeply for it. Many of us have made mistakes in our lives, and many of us have hurt others as well.
However, I believe this quote is still valid. Because now that we are awake, we have a choice in life. We can continue to let the past hold us prisoner and make us bitter. Or we can CHOOSE to accept this part of our lives as our particular life's lesson that we needed to go through in order to make us stronger and more aware. After all if you have never known pain, how does one know when they are not in pain.
What is the hardest thing to do for a good many people is to accept and let go those things that have harmed them in the past. It took me a long time to learn that lesson myself. Now I've learned that these things made me the person I am today. I had to go through all those experiences, both good and bad, in order to be stronger.
It may sound strange, but what we should be doing is thanking those people that have caused you pain. Thank them for waking you up so that you could see. And then let all the past go. Release all that bad energy and ground yourself to the here and now.
By releasing all that, you can move forward and then that quote will aid you on your journey forward. Its never too late to start living.
