The Mandala or “container of essence” may symbolize both the mind and body of Buddha
The mandala is older than history itself.
The following verse is taken from the “Tibetan Book of the Dead“
Oh you compassionate ones possessing the wisdom of understanding, the love of
compassion, the power of acting, and of protecting in incomprehensible measure,
one is passing through this world and leaving it behind. No friends does (s)he
have, (s)he is without defenders, without protectors and kinsmen. The light of
this world has set. (s)he goes from place to place, (s)he enters darkness, (s)he
falls down a steep precipice, (s)he enters a jungle of solitude, (s)he is
pursued by karmic forces, (s)he goes into a vast silence, (s)he is borne away on
the great ocean, (s)he is wafted on the wind of karma, (s)he goes where there is
no certainty, (s)he is caught in the great conflict, (s)he is obsessed by the
great affecting spirit, (s)he is awed and terrified by the messengers of death.
Existing karma has put hir into repeated existence and no strength does (s)he
have although the time has come to go alone.
