We come unbidden into this life, and if we are lucky we find a purpose beyond starvation, misery, and early death which, lest we forget, is the common lot.
The world is not looking for servants, there are plenty of these, but for masters, men who form their purposes and then carry them out, let the consequences be what they may.
There's nothing wrong in suffering, if you suffer for a purpose. Our revolution didn't abolish danger or death. It simply made danger and death worthwhile.
The purpose of life is undoubtedly to know oneself. We cannot do it unless we learn to identify ourselves with all that lives. The sum-total of that life is God.
