There are numerous ways to learn meditation. The best option to learn meditation is from a spiritual guru or person who has experience. You can look for Licensed Meditation Practitioner or look for a Yoga center in your area. The charges / fees for learning meditation can be really minimal as compared to other exercises. In case you can find a government run organisation, you can learn from an experienced professional and for free as well. All you would need to do is eat healthy diet, quit up smoking / drinking (if you do) and be punctual for your meditation classes. Learning with a meditation group can be really rewarding as you can share your experience with other people and learn from their experiences. Ofcourse you can leave the meditation classes if you feel like it is not for you. In case you are still making your mind, do visit the other post titled before you start meditation.
