done in the immediately previous life that is significant. What i~
said to be crucial in the process of rebirth is one's state of mind
at the time of death. It is understood that at death significant
acts performed during one's life tend to present, themselves to
one's mind. Certain kinds of action-for example, certain types
of murder -are regarded as so 'weighty' that they cannot but come
to mind at the time of death. In the absence of these what tends
to come to mind are one's habitual actions or the actions that
one performs close to the actual time of death. The widespread
Buddhist understanding that actions performed at the time of
death can be of crucial significance in determining the nature
of one's rebirth relates to various customs aimed at turning the
mind of a dying person to some meritorious action that he or she
has performed. Thus flowers, incense·, lamps, or chanting may
be offered on the dying person's behalf. And because the dead
person's new state may be short-lived or, in the Tibetan view, a
temporary 'in-between state', relatives and friends may continue
to perform actions for his or her benefit for some time after death.^14
The Tibetan belief in the bar-do or 'in-between state' (antarii-
bhava) is inherited from the Sarvastivadin Abhidharma and is
associated with the elaborate practices of the Bar-do Thos-grol,
the so-called Tibetan Book of the Dead. This notion of the 'in-
between state' was a subject of dispute among ancient Indian
schools of Buddhism; the Theravadins denied that it was co-
herent from an Abhidharma perspective, since an in-between
existence must be another kind of existence.^15
Essentially Abhidharma is a device for promoting mindfulness
and understanding. The study of Abhidharma encourages the
practitioner to pay attention to the kinds of mental states that
are occurring whatever he or she is doing. It also draws the prac-
titioner's attention to the way in which the spiritual process is
understood to unfold. To this extent it can be seen as simply
the elaboration of the analysis of the five aggregates and the
twelvefold chain of dependent arising.
One cannot make oneself think nice things or have beauti-
