Unrequited love is the meaning of life. We’re here to love but not to be loved, to give but not receive. Our mission in this world is to improve humanity and leave a better history than we found. Only selfless love has such power. Only love without interest or expectation of reward can change human beings... To give love without receiving love is the truest love and brings the greatest happiness there is in life.
It is indifference which is the cause of most of our unhappiness. Indifference to religion, to the happiness of others, and to the precious gift of freedom, and the wide liberty that is the inheritance of all in a free land. Are we our "Brother's Keeper"? We certainly are! If we had no regard for others' feelings or fortune, we would grow cold and indifferent to life itself. Bound up with selfishness, we could not hope for the success that could easily be ours.
The first real mental illumination I remember to have experienced was when I saw that the universe exists in each of its individual atoms - that is, the universe is the result of a few simple processes infinitely repeated. When a drop of water has been mathematically measured, every principle will have been used which would be called form in the measurement of the heavens. All life on the globe is sustained by digestion and assimilation; when by voluntary and traumatic action these stop death follows. The history of an individual mind is the history of the race. Know one thing in its properties and relations and you will know all things.
Life has neither material nor idealistic secrecy or mystery about it. Life is equal to itself only, hence perceiving its meaning is out of the question... The exaggeration of our mental abilities has given rise to what we perceive as “the problem” of discerning life’s purpose... If it is beyond our powers to disembowel love and beauty - we can only ravish them - it means that they are given to us not for cognition but for reflection. Similarly, the freedom of choice granted to man, a freedom denied the rest of the living species, is man’s task, a duty to exercise and fulfill, not merely an opportune option.
The confirmed prejudices of a thoughtful life are as hard to change as the confirmed habits of an indolent life; and as some must trifle away age because they trifled away youth, others must labor on in a maze of error because they have wandered there too long to find their way out.
