“Everything passes. Everything experiences the birth and death cycle.”

Evolution (1895; 1909)
Context: Thus life by life and love by love
We passed through the cycles strange,
And breath by breath and death by death
We followed the chain of change.
Till there came a time in the law of life
When o’er the nursing sod,
The shadows broke and soul awoke
In a strange, dim dream of God.

Statement before 1955, as quoted in God Speaks : The Theme of Creation and Its Purpose (1973), p. 266.

Context: Whether there have been 26 Avatars since Adam, or 124,000 Prophets, as is sometimes claimed, or whether Jesus Christ was the last and only Messiah, or Muhammad the last Prophet, is all immaterial and insignificant when eternity and reality are under consideration.
It matters very little to dispute whether there have been ten or twenty-six or a million Avatars. The truth is that the Avatar is always one and the same, and that the five Sadgurus bring about the advent of the Avatar on earth. This has been going on cycle after cycle, and millions of such cycles must have passed by, and will continue to pass by, without affecting eternity in the least.

Las dificultades también pasan, como todo pasa, sin dificultad.

Context: Most people don't realize that the slaughter plant is much gentler than nature. Animals in the wild die from starvation, predators, or exposure. If I had a choice, I would rather go through a slaughter system than have my guts ripped out by coyotes or lions while I was still conscious. Unfortunately, most people never observe the natural cycle of birth and death. They do not realize that for one living thing to survive, another living thing must die.
