Meditation is one of the top mindfulness practices. I have been following meditation podcasts and iTunes albums for several years and these are the top three I have personally found to be most effective. Meditation can be difficult to begin and hard to stick to but these meditations have been able to both introduce me to a regular practice and keep me going.
