Life is something you measure not in years but in precious moments - and in how you value those moments. The responsibility for making such moments meaningful is yours alone. There are no definitions of failure or success except the ones you specify for yourself. You are the meaning of your own life.
Instinct gave place temporarily to a system of habits, each one of which became contingent, their convergence of which became contingent, their convergence towards the preservation of society being alone necessary, and this necessity bringing back instinct with it. The necessity of the whole, felt behind the contingency of the parts, is what we call moral obligation in general - it being understood that the parts are contingent in the eyes of society only; to the individual, into whom society inculcates its habits, the part is as necessary as the whole.
Your greatness is measured by your kindness - Your education and intellect by your modesty - Your ignorance is betrayed by your suspicions and prejudices - Your real caliber is measured by the consideration and tolerance you have for others.
My reason teaches me that land cannot be sold. The Great Spirit gave it to his children to live upon and cultivate as far as necessary for their subsistence, and so long as they occupy and cultivate it they have the right to the soil, but if they voluntarily leave it then any other people have a right to settle on it. Nothing can be sold, except things that can be carried away.
With our finite minds we cannot presume to know if there is a Purpose. We sense, however, the presence of something greater than we can comprehend, a force as yet unknown to us - perhaps even to be unknown. So we accept our situation, learn from it, and do the best we can, resting on faith, despair, or cynicism, depending on the individual. Overriding all this must be an obligation - self-imposed or externally impressed - to do the best one can for others, to relieve suffering and to exercise compassion. We are all in this together, for life is a common, not an individual, endeavor.
On life's journey faith is nourishment, virtuous deeds are a shelter, wisdom is the light by day and right mindfulness is the protection by night. If a man lives a pure life nothing can destroy him; if he has conquered greed nothing can limit his freedom.
