It is in the nature of things, however dear they may be to us, that we must separate from them, leave and depart from them. Anything that is born, that is formed and brought into being, contains within itself the qualities naturally associated with its own dissolution.
Never have anything to do with likes and dislikes. The absence of what one likes is painful, as is the presence of what one dislikes. Therefore don’t take a liking to anything. To lose what one likes is hard, but there are no bonds for those who have no likes and dislikes. From preference arises sorrow, from preference arises fear, but he who is freed from preference has no sorrow and certainly no fear.
When the senses touch sense objects and the thoughts touch thought objects, the fires of lust and desire are kindled. Your ears hear praises of yourselves and then your thoughts think of self importance and you are fearful lest you lose the self-importance. You forget that this self is not the true self of you which is universal and deathless.
Once you understand non-self, then the burden of life is gone. You'll be at peace with the world. When we see beyond self, we no longer cling to happiness and we can truly be happy. Learn to let go without struggle, simply let go, to be just as you are - no holding on, no attachment, free.
If a man cares not if things are thus and not thus, then provided he has no harsh thoughts, he has indeed found happiness. He has certain security for he has found freedom from grief and care. Truly, he has overcome the world.
Improvement or degeneration, happiness or misery, are all the results of our deeds. We ourselves are moulders of our fate. No one else is to be blamed for our misery, or praised for our happiness.
Conditions all go their own natural way. Whether we laugh or cry over them, they just go their own way. And there is no knowledge of science that can prevent this natural course of things. Everything falls apart in the end.
All men tremble at punishment, all men fear death; remember that you are like unto them, and do not kill, nor cause slaughter. He who, seeking his own happiness, punishes or kills beings who also long for happiness, will not find happiness after death.
