Meditation takes on many, many forms. It can be deep breathing for a few minutes, singing or listening to soothing music. All in all it is a great tool to ease and calm the mind whatever form you choose to use. I can say personally that meditation was the most effective thing I did that finally got me a good night's sleep.
Though the need for sleep has been a constant throughout human history, how we feel about it has gone through dramatic changes over the years. We're now in the process of renewing our estranged relationship, especially as science, in the last two decades or so, has validated much of the ancient wisdom about the importance of sleep. Now that we have the means to get, relative to most of human history, the most unprecedentedly blissful sleep ever, we should allow ourselves to enjoy it. We live in a time in which we're plugged in and hyperconnected, often from the moment we wake up until the instant we drift off. Let's savor and safeguard sleep, not just for its performance benefits but for the special way it allows us to connect with ourselves. During the daytime technology allows us to travel across distance and space, but during the nighttime our dreams allow us to travel across time, spanning and connecting different parts of ourselves, allowing our senses of intuition and wisdom to flourish.
