Some of the best advice I’ve heard about getting better at prayer and meditation was from a speaker at a conference I went to in high school. He advised us to create a “sanctuary in our room.” In other words, create a nook you can go to that is only used for prayer or meditation. In that way, you will be better able to focus and hopefully spend less time playing “tie down the monkeys” with your stray thoughts.
There used to be this tree a short walk from my house that bordered a wheat field. It had long, drooping branches and in the summer, its thick leafy branches touched the top of the wheat, creating a secret little spot in the shade. I went there to meditate as often as I could manage.
When I couldn’t manage, I took all the pictures off of one of the walls in my room and set a chair there, facing the corner.
These days, I find sitting on the floor in the dark, or with a candle or incense, more effective than the chair in the corner. But I still prefer to meditate outside when possible, if I can find somewhere I won’t be disturbed.
