When you ask what Buddhism really is, it's a hard question to answer in a few words. You have to come back to this process of meditation because there is the crux, the fulcrum of Buddhism, the heart of Buddhism. .........
The Buddha taught that it is attachment that causes suffering and letting go is the cause for happiness and the way to enlightenment. Letting go! So often people have asked how do you let go? What they really mean is, why do you let go? It's a difficult question to answer and it will never be answered in words. Instead I answer that question by saying "Now is the time to meditate, cross your legs, be in the present moment," because this is teaching people what letting go is all about. Moreover, the final moments of the meditation are the most important. Please always remember this. In the last few minutes ask yourself, "How do I feel?" "What is this like and why?" "How did this come about?"
People meditate because it’s fun, it's enjoyable. They don't meditate to "get something out of it," even though when you meditate there are a lot of good benefits to be had such as health benefits or reducing stress in your life. Through meditation you become less intolerant, less angry. But there is something more to it than that - it's just the sheer fun of it!
When I was a young monk that's what made me become a Buddhist. It was inspiring to read the books but that was not good enough. It was when I meditated and became peaceful, very peaceful, incredibly peaceful, that something told me that this was the most profound experience of my life. I wanted to experience this again. I wanted to investigate it more. Why? Because one deep experience of meditation is worth a thousand talks, or arguments, or books, or theories.
The things you read in books are other people's experiences, they are not your own. They're words and they might inspire, but the actual experience itself is truly moving. It's truly earth shattering because it shatters that which you’ve rested on for such a long time. By inclining along this path of meditation you’re actually learning what letting go really is.
For those of you who have difficulty meditating, it's because you haven’t learned to let go yet in the meditation. Why can't we let go of simple things like past and future? Why are we so concerned with what someone else did to us or said to us today? The more you think about it, the more stupid it is. You know the old saying, "When someone calls you an idiot, the more times you remember it, the more times they've called you an idiot!" If you let it go immediately, you will never think about it again. They only called you an idiot at most once. It's gone! It's finished. You're free.
Why is it that we imprison ourselves with our past? Why can't we even let that go? Do you really want to be free? Then acknowledge, forgive and let go, what I call in Australia the "AFL Code"  - Acknowledge, forgive, and let go of whatever has hurt you, whether it's something that somebody has done or said, or whether it's what life has done. For instance, someone has died in your family and you argue with yourself that they shouldn't have died. Or you've lost your job and you think without stop that that shouldn't have happened. Or simply something has gone wrong and you are obsessed that it's not fair. You can crucify yourself on a cross of your own making for the rest of your life if you want to; but no one is forcing you to. Instead you can acknowledge forgive and learn in the forgiving. The letting go is in the learning. The letting go gives the future a freedom to flow easily, unchained to the past
