Unlike many of other Mother Nature's animals, we have evolved to create time for ourselves in which to contemplate the past and think about our future. In meditation we often try to focus in on the present, but as a change of pace, try meditating on the past. Take an old record or CD that you used to play on repeat in your younger years. Sit in a comfortable position and close your eyes. Let the music take you on a journey to your past. What do you see? What are the smells that tickle your nose? What are the feelings associated with the music?
I would love to hear how it goes!
