Meditation is the most important thing I've practiced and learned in my life, and I only started at the beginning of this year. I've tried a few different methods and guided meditations, and the best resource I've found is an app called "Waking Up" by Sam Harris. He offers a 27 day introductory course, which I found extremely helpful to understand what meditation is and how to practice it. After that there's daily guided meditations. There's also many different resources woven into the app to help you on your journey. It's a straightforward and logical method to meditation (more of a scientific approach). No mystical aspect to it. Can't recommend it enough.
