This SHORT guided meditation has been my go-to for over 5 years. As a beginner, this meditation helped me focus, and was a perfect introduction to the feelings meditation should procure. I often use it to teach beginners. 

Then, in times when I did not practice enough, it was my re-introduction to meditation. I also often listen to it in times of stress, when my mind is more likely to focus on negative things. With this meditation, I know I will have a certain guidance, which will keep mental chatter at bay. Enjoy!
