we can say there is a little invisible button inside
ourselves that has to be pushed at the time of initiation,
as per request. And then everything will be opened,
just like "open sesame." In the olden days,
people used different parables to describe the opening
of the inner eye, the wisdom eye. They called it the
rediscovery of the wish-fulfilling gem, or opening
the gate to Heaven, or the key to Heaven, etc."
from "The Supreme Master Ching Hai
1993 World Tour", Series V, page 41
pearl and wish-fulfilling gem signifies our Buddha
nature. The time that we attain muni pearl is when
we are enlightened. The phrase, "when the flower
blossoms, one shall see Buddha." means attaining
muni pearl. And why does Buddha nature relate to muni
pearl? Because after reclaiming Buddha nature, like
a wish-fulfilling gem, we can get Whatever we want
and become whatever we want to be. Whatever we wish
will be fulfilled immediately. Even before we think
of it, it is already there. Therefore, it is called
muni pearl. Muni pearl is a Sanskrit name, in Chinese
called wish-fulfilling gem. If we attain muni pearl,
we will have everything."
