One of my favorite meditative/mindful techniques I use, especially when I find myself getting bored or overly excited, is the Red Rubber Ball. I learned this from an Aikido-ka about 22 years ago and I love it.
All you have to do is imagine you have a red rubber ball in your hara. This is three inches below your navel and three inches in, approximately. If you find yourself bored or nervous, like what can happen to me, just bring your focus to the red rubber ball.
Sometimes I breath into it and when I inhale I make it expand and when I exhale I make it contract. Now, if you want you can use different colors. Sometimes for a cooling, calm feeling I will pick green or blue and breath into it or let its energy bath me in calmness. You are only limited by your imagination.
Over the years I discovered I could also 'magnetize' the ball and make it attract a healing, insight into a problem or even money. However you picture magnetization, imagine it and see it attracting what you want and how great it feels! The feeling of the healing or insight or money already being here is very important. It is the attractor factor inside the ball.
