When the senses contact sense objects, we experience cold or
heat, pleasure or pain. These are fleeting; they come and go. Bear them
patiently.
The person who is unaffected by the sense objects, who is
the same in pleasure and pain, is truly wise and fit for immortality. Assert
your strength to realize this.
The impermanent has not reality; reality lies in the
eternal. Those who have seen the boundary between these two have attained the
end of all knowledge.
Realize that which pervades the universe and is
indestructible; no power can affect this unchanging, imperishable Reality.
The body is mortal, but he who dwells in the body is said to
be immortal and immeasurable.
