Thus, after a pa¤ca-dvàra vãthi, a mano-dvàra vãthi quickly
follows it retaking the sense-object of the pa¤ca-dvàra vãthi as a
past object.
Then the second mano-dvàra vãthi follows suit observing the
new image and the old impression together.
Then the third mano-dvàra vãthi quickly follows again
observing the form and the shape of the sense-object.
Then the fourth mano-dvàra vãthi follows considering the name
associated with the object. If necessary many mano-dvàra vãthis
quickly occur in succession considering the features of the object
in detail and also the time and the place connected with the object
if he has encountered it before.
Only after these many secondary mano-dvàra vãthis, does one
know the object together with form, shape, name and other details.
Considering the fact that cittas can occur at a tremendous
rate of more than a thousand billion times per eye-wink and a
mano-dvàra vãthi contains only about 10 vãthi cittas, more than a
billion vãthis can occur in a fraction of a second. So we can know
the objects we see or hear almost instantly and we even think
that we see and hear simultaneously.
Practical Verification
That pa¤ca-dvàra vãthis and mano-dvàra vãthis are occurring at a
tremendous rate incessantly in a person can be verified by the
person himself. As cittas are invisible even under the best
microscope, an instrument more powerful than the latest
electronic microscope will be necessary to observe the cittas.
This instrument is none other than the mind itself accompanied
by upacàra-samàdhi (neighbourhood or access-concentration) or
better by jhàna-samàdhi (meditative absorption).
