Mindfulness meditation is not a thing — it is an activity of doing. It is a key to an eight faceted practice capable of freeing us from discontent. Being mindful is being deeper than the ocean, stronger than practiced aversion, quicker than chronic bad habits, and easier than pie!
The Mindfuling podcast frequently includes guided meditation, talks, interviews, sounds, and prior to episodes M#180 a fictional serial radio drama entitled Hot Zombies Cool Buddhas. More at http://www.mindfuling.org
Please note: No podcast is a substitute for real live meditation with other humans. But it is a nice supplemental for the audio-minding!
