Through my own observations. I am convinced that an absolutely honest and direct inquiry into oneself will lead to understanding.
If you want to be immortal live a life worth remembering
Be like water, my friend.
A quick temper will make a fool of you soon enough.
What is true stillness? Stillness in movement.
Be like water making its way through cracks. Do not be assertive, but adjust to the object, and you shall find a way round or through it. If nothing within you stays rigid, outward things will disclose themselves.
