were not so in its nature, there would be no
difference between life and death, for life on the
surface is nothing but the phenomena of contrast.
This, then, is another way of expressing what is the
purpose of life.
2. Life In This World
One may try to see from the point of view of another
as well as from one's own, and so give freedom of
thought to everybody because one demands it oneself;
one may try to appreciate what is good in another,
and overlook what one considers bad; if somebody
behaves selfishly towards one, one may take it
naturally, because it is human nature to be selfish,
and so one is not disappointed; but if one appears
oneself to be selfish, one should take oneself to task
and try to improve. There is not anything one should
not be ready to tolerate, and there is nobody whom
one should not forgive. Never doubt those whom you
trust; never hate those whom you love; never cast
down those whom you once raise in your estimation.
Wish to make friends with everyone you meet; make
an effort to gain the friendship of those you find
difficult; become indifferent to them only of you
cannot succeed in your effort. Never wish to break
the friendship once made.
