The heights of the spirit can only be climbed by passing through the portals of humility. You can only acquire right knowledge when you have learnt to esteem it.
~ from KNOWLEDGE OF THE HIGHER WORLDS AND ITS ATTAINMENT by Rudolf Steiner
Gratefulness has three steps: not missing the opportunity, appreciating the opportunity, and using or enjoying the opportunity. By this method we come fully alive, full of joy, which is what we are all longing for.
