Christianity taught the capacity, the element, to love the All-perfect without a stingy bargain for personal happiness. It taught that to love Him was happiness;--to love Him in others' virtues.
If a thing happens once, it can happen again. If any human being has ever realised perfection, we too can do so. If we cannot become perfect here and now, we never can in any state or heaven or condition we may imagine.
Thus all things are subject to death, sorrow and suffering. I became aware that I too was of the same nature, the nature of beginning and end. What if I searched for that which underlies all creation, that which is nirvana, the perfect freedom from unconditioned existence?
Even the clearest and most perfect circumstantial evidence is likely to be at fault, after all, and therefore ought to be received with great caution. Take the case of any pencil, sharpened by any woman; if you have witnesses, you will find she did it with a knife; but if you take simply the aspect of the pencil, you will say that she did it with her teeth.
According to most philosophers, God in making the world enslaved it. According to Christianity, in making it, He set it free. God had written, not so much a poem, but rather a play; a play he had planned as perfect, but which had necessarily been left to human actors and stage-managers, who had since made a great mess of it.
Lastly, I would address one general admonition to all: that they consider what are the true ends of knowledge, and that they seek it not either for pleasure of the mind, or for contention, or for superiority to others, or for profit, or fame, or power, or any of these inferior things: but for the benefit and use of life; and that they perfect and govern it in charity.
