The first video contains a basic meditation timer for mindfulness meditation and other practices.
Please note that the bell chimes at the start and 2′, 5′, 10′, 20′ and 30′.
This is not a guided meditation and there is no music.
As a bonus, you can watch the slowly moving images as a form of mindfulness practice.
For background meditation music or to practice listening meditation, try this video.
Tip: on some devices, you can play both videos together.
