Man's real nature is primarily spiritual life,
which weaves its threads of mind to build a
cocoon of flesh, encloses its own soul in the cocoon,
and, for the first time, the spirit becomes flesh.
Understand this clearly: The cocoon is not the silkworm;
In the same way, the physical body is not man but
merely man's cocoon. Just as the silkworm will break
out of its cocoon and fly free, so, too, will man
break out of his body-cocoon and ascend to the spiritual
world when his time is come. Never think that the
death of the physical body is the death of man.
Since man is life, he will never know death.
