In some schools of Buddhism, bardo
is explained as an intermediate or transitional state that occurs between death
and rebirth…it is a concept which began soon after the death of Buddha with
many of the earlier Buddhist groups accepting the existence of such an
intermediate state…others schools outright rejected the idea…in layman terms,
"bardo" is the state of existence that happens between two lives on
earth…according to Tibetan tradition, this state occurs after death and before
one's next birth…when one's consciousness it is said, is not connected with a
physical body…during this time, one experiences a variety of phenomena…there
are different types of bardo…the first is from conception until the very last
breath…the second is a dream state…the third is meditation and it is said that
it is generally only experienced by those that have meditated…at the moment of
death is the fourth bardo, the fifth is the luminosity of the true nature which
begins after the final breath… the sixth bardo is the process of
transmigration…interesting…if you need more details, you can read all the intricacies
