If you are looking for peace in a busy life, or simply want to set some free space in your brain, the following apps might be useful.
– Headspace: guided 10-minute meditations. Pre-recorded by a British young man. It has a ten-day trial period, but charges a fee afterwards.
– Insight Timer: provides free, pre-recorded guided meditation by famous meditation practitioners (Thich Nhat Hahn, for example). You can also share your life experiences and thoughts on meditation on a discussion forum.
