If it's painful, you become willing not just to endure it but also to let it awaken your heart and soften you. You learn to embrace it.
As Buddhism moved from one culture to another, it always adapted.
We are one blink of an eye away from being fully awake
You build inner strength through embracing the totality of your experience, both the delightful parts and the difficult parts.
In order to have compassion for others, we have to have compassion for ourselves.
It's also helpful to realize that this very body that we have, that's sitting right here right now... with its aches and it pleasures... is exactly what we need to be fully human, fully awake, fully alive.
