Hello,

I'm Kendra “KSL.” I'm new to Zaadz and Tonglen Tidbits. A Buddist friend of mine told me about Tonglen a couple years ago and I found it very interesting. Never really studied anything more about it since. I want to learn more.

Question…
Is Tonglen affective to use on yourself for chronic pain or is it something you use more to understand the pain of others?
