'functions of consciousness', as
exercised within a process of consciousness or cognitive series (cittavīthi).
In the Abhidhamma Com. and Vis.M. XIV the following functions are mentioned:
- rebirth (patisandhi),
- subconsciousness (bhavanga),
- advertence (āvajjana),
- seeing, hearing, smelling, tasting, body-consciousness;
- receiving (sampaticchana),
- investigating (santīrana),
- determining (votthapana),
- impulsion (javana),
- registering (tadārammana),
- dying (cuti).
A single unit of sense-perception (e.g. visual
consciousness), being conditioned through a sense-organ and its corresponding
object, forms in reality an extremely complex process, in which all the single
phases of consciousness follow one upon another in rapid succession, while
performing their respective functions, e.g.:
"As soon as a visible object has entered the range of
vision, it acts on the sensitive eye-organ (cakkhu-pasāda), and
conditioned thereby an excitation of the subconscious stream (bhavanga-sota) takes
place.
"As soon, however, as sub consciousness is broken off,
the functional mind-element (s. Tab. I, 70), clinging the object and breaking
through the subconscious stream, performs the function of 'adverting' the mind
towards the object (āvajjana).
"Immediately thereupon there arises at the eye-door, and
based on the sensitive eye-organ, the eye-consciousness, while performing the
function of 'seeing' (dassana).... Immediately thereafter there arises
the mind-element (Tab.I, 39, 55) performing the function of 'receiving' (sampaticchana)
the object of that consciousness....
''Immediately thereafter there arises... the
mind-consciousness-element (Tab. I, 40, 41, 56), while 'investigating' (santirana)
the object received by the mind-element...
"Immediately thereafter there arises the functional,
rootless mind-consciousness-element (Tab. I, 71), accompanied by indifference,
while performing the function of 'determining' (votthapana) the
object......
"Now, if the object is large, then immediately
afterwards there flash forth 6 or 7 'impulsive moments' (javana-citta),
constituted by one of the 8 advantageous, or 12 disadvantageous, or 9 functional
classes of consciousness (Tab. I, 1-8; 22-23; 72-80).
''Now, if at the end of the impulsive moments, the object at
the five-sense doors is very large, and at the mind-door clear, then there
arises, once or twice, one of the 8 root-accompanied, karma-resultant classes of
consciousness (Tab. I, 42-49) of the sense-sphere, or one of the 3 rootless
karma-resultant mind-consciousness-elements (Tab. I, 40, 41, 56).... Because
this consciousness after the vanishing of the impulsive moments, possesses the
ability continuing with the object of the sub consciousness, taking the object of
the sub consciousness as its own object, therefore it is called 'registering' (tadārarmmana,
lit. 'that object', or 'having that as object')" (Vis.M. XIV, 115ff).
If, however, the sense-object is weak, then it reaches merely
the stage of 'impulsion' (javana), or of 'determining' (votthapana); if
very weak, only an excitation oft the sub consciousness takes place.
The process of the inner or mind-consciousness, i.e. without
participation of the 5 physical senses, is as follows: in the case that the
mind-objeet entering the mind-door is distinct, then it passes through the
stages of 'advertence at the mind-door' (manodvārāvajjana), the
'impulsive stage' and the 'registering stage', before finally sinking into the
subconscious stream. - (App.: citta-vīthi).
