Suffering has a noble purpose: the evolution of the consciousness and the burning up of the ego. - Eckhart Tolle

When you walk though a forest that has not been tamed and interfered with by man, you will see not only abundant life around you, but you will also encounter fallen trees and decaying trunks, rotting leaves and decomposing matter at every step. (Ch 9)

The primary cause of unhappiness is never the situation but your thoughts about it. Be aware of the thoughts you are thinking. Separate them from the situation, which is always neutral. There is the situation or the fact, and here are my thoughts about it. Life isn't as serious as the mind makes it out to be.

Do you need more knowledge? Is more information going to save the world, or faster computers, more scientific or intellectual analysis? Is it not wisdom that humanity needs most at this time? But what is wisdom and where is it to be found? Wisdom comes with the ability to be still. Just look and just listen. No more is needed. Being still, looking, and listening activates the non-conceptual intelligence within you. Let stillness direct your words and actions. (Ch 1)
