For anyone interested in meditation, I’d highly recommend listening to binaural beats.
The videos linked below range from about 10-20 minutes in length. The sounds in each track alters brain waves in a way that relaxes the listener  (so they are most effective when listened to through a set of headphones). These sets are designed to aid the listener into achieving a meditative state.

The sound is played at a different sound frequency through each earphone, causing the two sides of the brain to interact to hear the pitch, creating hemisphere synchronicity.

My goal when I initially started practicing meditation was to calm my thoughts and develop some of this “self awareness” that all the yogis kept raving about. I practiced whilst listening to binaural beats and got exactly what I was aiming for. A calm and self-reflective mind.

I’d strongly recommend giving one of these a try – they’re only short but still effective!

If you’re looking for something more specific, such as a set that will help you with sleeping or being more awake and focused, check the image below to see what frequencies will induce the state of mind you want to achieve. There are even binaural beat tracks that are aimed at inducing lucid dreaming and even weight loss!
