It is worthwhile for one to make an effort to achieve happiness. Just as the purpose of a plant is to grow, so it is that the main purpose of every human being is to survive and to grow until death.
Though the Life Force supplies us with its own purpose, it has no other brains to work with than those it has painfully and imperfectly evolved in our heads.
And let there be no purpose in friendship save the deepening of the spirit. For love that seeks aught but the disclosure of its own mystery is not love but a net cast forth: and only the unprofitable is caught.
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.
Let only that little be left of me whereby I may name thee my all. Let only that little be left of my will whereby I may feel thee on every side, and come to thee in everything, and offer to thee my love every moment. Let only that little be left of me whereby I may never hide thee. Let only that little of my fetters be left whereby I am bound with thy will, and thy purpose is carried out in my life--and that is the fetter of thy love.
There are no accidents, all things have a deep and calculated purpose; sometimes the methods employed by Providence seem strange and incongruous, but we have only to be patient and wait for the result: then we recognize that no others would have answered the purpose, and we are rebuked and humbled.
