Be not the slave of your own past. Plunge into the sublime seas, dive deep and swim far, so you shall come back with self-respect, with new power, with an advanced experience that shall explain and overlook the old.
~Ralph Waldo Emerson~
Find a comfortable seat on a cushion or mat. Lengthen up through the spine, open the heart center, and close the eyes. Begin to go inward and notice what you are feeling. Start your deep breathing practice, counting 15-20 slow deep breaths.
Think of 3 aspects of your past the you would like to let go. These aspects can be anything that comes to the mind, a negative event, a conversation, a hurt feeling, ect. be careful not to judge what might come up. With these 3 aspects visualize your self placing each of them in 3 different balloons. As each new thought comes up visualize yourself placing it in the balloon and slowly letting it go. Watch each balloon slowly rise to the sky, one at a time, and slowly float away.
Stay here with this meditation listening to your breath and monitoring the thoughts that might come and go. Go back to the balloon visualization again if needed. In your last 3-5 minutes imagine 3 new aspects that your would like to bring into your life, again trying not to judge what might come up, letting your thoughts float freely. Continue to monitor your breath and breathe in a sense of relaxation and release with each breath.
