Buddhist-Meditation-Systematic-and-Practical

(The following are from the Diamond Sutra, translated
by E. Conze.)
"So should one view what is conditioned:
"As a dream": There is nothing one can hold to when
one awakens after a dream, but still one may remember
some of its details. The voidness of its nature is the
inability to grasp anything therein; and the fullness of its
conditions is having such conditions gathered which
produced that particular dream.
"As an illusion": A magician produces some phenomena
which to ordinary people, not knowing his methods,
may seem to be real; this is the fullness of conditions. If
you examine carefully what he is doing, unreal—this is
the voidness of their nature.
"As a bubble": Outside, it is round as a ball, but inside
quite empty. The outer appearance is the fullness of
conditions and the inside the voidness of nature. In the
Vajrayana, this particular method is further developed in
meditations on the body as a bubble.
"As a shadow": Our shadows never leave us and we can
see them quite plainly but cannot ever catch them.
Seeing that they have happened is their fullness of
conditions while being unable to catch them is their
voidness. Reflections in a mirror are very similar to this
example.
