By respect for life we become religious in a way that is elementary, profound and alive. Impart as much as you can of your spiritual being to those who are on the road with you, and accept as something precious what comes back to you from them.

We should all be thankful for those people who rekindle the inner spirit. - Albert Schweitzer
