on PAGE TWENTY, Sayadaw again notes that if we know materiality well, we can move on to mentality. He adds more about noting the sense bases and doors (sometimes the same word in other commentaries). I found a reference I liked in a Vipassana guide on Buddhanet:
the Buddha said. When you see, say, a very beautiful rose you realise the rose is very beautiful. Its scent is very sweet. When you judge like that there arises a pleasant feeling about the rose. When you feel a pleasant feeling what will arise? Attachment, to what? To the rose. To the feeling or to the rose? To the rose. And pleasant feeling, attachment, arises dependent on that feeling. This attachment is to the rose. Then if the flower is not beautiful, is ugly and produces a bad smell, when you see it how do you feel, pleasant or unpleasant? Unpleasant. You'll judge the flower is very ugly, `I don't want to see it.` Then what mental state arises? Aversion. Anger.
This all happens due to a 'natural law of consciousness', a cognitive process of the sense doors. (vithi). How does that work? From a commentary on the Abhidhamma:
4. Thought-processes
According to Abhidhamma ordinarily there
is no moment when we do not experience a particular kind of consciousness, hanging on to
some object - whether physical of mental. The time-limit of such a consciousness is termed
one thought-moment. The rapidity of the succession of such thought-moments is hardly
conceivable by the ken of human knowledge. Books state that within the brief duration of a
flash of lightning, or in the twinkling of an eye billions of thought-moments may arise
and perish.
Each thought-moment consists of three minor
instants (khanas). They are uppada (arising or genesis), thiti
(static or development), and bhanga (cessation or dissolution).
Birth, decay, and death* correspond to these
three states. The interval between birth and death is regarded as decay.
Immediately after the cessation stage of a
thought-moment there results the genesis stage of the subsequent thought-moment. Thus each
unit of consciousness perishes conditioning another, transmitting at the same time all its
potentialities to its successor. There is, therefore, a continuous flow of consciousness
like a stream without any interruption.
[*These three stages correspond to the Hindu
view of Brahma (Creator). Vishnu (Preserver) and Siva (Destroyer).]
When a material object is presented to the
mind through one of the five sense-doors, a thought-process occurs, consisting of a series
of separate thought-moments leading one to the other in a particular, uniform order. This
order is known as the citta-niyama (psychic order). As a rule for a complete
perception of a physical object through one of the sense-doors precisely 17
thought-moments must pass. As such the time duration of matter is fixed at 17
thought-moments. After the expiration of that time-limit, one fundamental unit of matter
perishes giving birth to another unit. The first moment is regarded as the genesis (uppada),
the last as dissolution (bhanga), and the interval 15 moments as decay or
development (thiti or jara).
As a rule when an object enters the
consciousness through any of the doors one moment of the life-continuum elapses. This is
known as atita-bhavanga. Then the corresponding thought-process runs
uninterruptedly for 16 thought-moments. The object thus presented is regarded as 'very
great.'
If the thought-process ceases at the
expiration of javanas without giving rise to two retentive moments (tadalambana),
thus completing only 14 moments, then the object is called 'great'.
Sometimes the thought-process ceases at the
moment of determining (votthapana) without giving rise to the javanas,
completing only 7 thought-moments Then the object is termed 'slight.'
At times when an object enters the
consciousness there is merely a vibration of the life-continuum. Then the object is termed
'very slight.'
When a so-called 'very great' or 'great'
object perceived through the five sense-doors, is subsequently conceived by the mind-door,
or when a thought process arising through the mind-door extends up to the retentive stage,
then the object is regarded as 'clear'.
When a thought process, arising through the
mind-door, ceases at the javana stage, the object is termed 'obscure'.
When, for instance, a person looks at the
radiant moon on a cloudless night, he gets a faint glimpse of the surrounding stars as
well. He focuses his attention on the moon, but he cannot avoid the sight of stars around.
The moon is regarded as a great object, while the stars are regarded as minor objects.
Both moon and stars are perceived by the mind at different moments. According to
Abhidhamma it is not correct to say that the stars are perceived by the sub-consciousness
and the moon by the consciousness.
WHOA!
