Ajahn Brahm wrote "... fear is staring at the brick wall of our future and seeing only what might go wrong." He tells a story about building a brick wall with mortar and trowel. When it was done, all he could see out of the thousand bricks he laid were the two that he got wrong. He felt they spoiled the whole wall. But when a visitor casually admired the wall, he found he could see the whole thing and not just the bricks he got wrong. I used his brick wall story to make a meditation about the worry I couldn't seem to shake.
Ajahn Brahm uses this analogy through the whole book and we can too. It can be a brick wall of accomplishment, a brick wall of the past, or any other brick wall we need.
There are no right or wrong ways to do a meditation. The instructions are guidelines; adapt them to who you are and to your needs at that particular time. Be curious about the process itself.
Remember most meditations become richer the more you practice them. They reveal more of themselves. It can take practice to remember to do a meditation when you need to, and it can take practice to go through the steps. But that's why it is called practice, and for most of us, we practice for the rest of our lives.
