The Triratna Buddhist Community has a fabulous on-line library of audio Dharma talks hosted at Free Buddhist Audio. They have well over 1,000 talks from Buddhist centres around the world. But if that’s a bit overwhelming (where exactly should you start?!) they also run two weekly Podcasts - FBA Talks and Dharmabytes. The first is a recommended talk chosen by the FBA team; the second, what they describe as “bite-sized Dharma”.
They say - “Podcasts are a fantastically easy way to access our talks! It’s safe (no viruses) and really simple – one click and you’ll be subscribed to a regular download service that delivers great Dharma automatically, straight to your computer. Copy the talks from there to your iPod or mp3 player, and away you go – your own portable archive.”
