Knowing your limits is good self-wisdom to develop. Expanding those boundaries takes practice and dedication. Other times I come to the deeper resolution and ask, "Why am I punishing myself with all this?" It is a relief to release from meaninglessness, and see more clearly what matters in life.

Thank you for sharing. I have never heard of this type of practice being pursued by people living modern lives. Sounds like a recipe for a self-inflicted ongoing panic attack or medical emergency.
