[LoohornePharp]

Could you elaborate on this a little more on this definition of consciousness?

Let me go further into this with the Buddha's comparison from MN 38 of how (according to him), an uninstructed person, a person in training, and an arahant treat pleasurable, displeasurable, and neutral sense data that arises through each of the sense systems:

"Bhikkhus, that child grows and his faculties mature and he plays games that children play, such as playing with toy ploughs, turning somersaults, making toy wind mills with palm leaves, making small carts and bows. Bhikkhus, that child grows and his faculties mature [further] and the youth enjoys the five strands of sense pleasures; he lives enticed by pleasing and agreeable forms cognizable by eye consciousness, agreeable sounds cognizable by ear consciousness, agreeable smells cognizable by nose consciousness, agreeable tastes cognizable by tongue consciousness and agreeable touches cognizable by body consciousness.

"On seeing a form with the eye he becomes greedy for a pleasant form, or averse to a disagreeable form. He abides with mindfulness of the body not established and with a limited mind. He does not know the deliverance of mind nor the deliverance through wisdom as it really is, where unwholesome states cease completely. He follows the path of agreeing and disagreeing and experiences whatever feeling that arises - pleasant, unpleasant, or neither unpleasant nor pleasant. Delighted and pleased with those [pleasant] feelings he appropriates them. This arouses interest in those feelings. That interest for feelings is clinging. From clinging, there arises becoming, from becoming arises birth, from birth old age, sickness and death, grief, lament, unpleasantness, displeasure and distress. Thus arises the complete mass of dukkha.

"Hearing a sound with the ear, smelling a smell with the nose, tasting a taste with the tongue, feeling a touch with the body, thinking a thought with the mind, he becomes greedy for a pleasant experience, or averse to a disagreeable one. He abides with mindfulness of the body not established and with a limited mind. He does not know the deliverance of mind nor the deliverance through wisdom as it really is, where unwholesome states cease completely. He follows the path of agreeing and disagreeing and experiences whatever feeling that arises - pleasant, unpleasant, or neither unpleasant nor pleasant. Delighted and pleased with those [pleasant] feelings he appropriates them. This arouses interest in those feelings. That interest for feelings is clinging.

"A householder, or a householder's son, or one born into some other family, hears the Dhamma. Having heard the Dhamma, he gains faith in the Tathagata. Endowed with such faith, he reflects: 'The household life is crowded, a path of dust. Going forth is like the open air. It is not easy for one dwelling at home to lead the perfectly complete, perfectly purified holy life, bright as a polished conch. Let me then shave off my hair and beard, put on saffron robes, and go forth from the household life into homelessness.'

"After some time he abandons his accumulation of wealth, be it large or small; he abandons his circle of relatives, be it large or small; he shaves off his hair and beard, puts on saffron robes, and goes forth from the household life into homelessness.

"When he has thus gone forth, he lives restrained by the rules of the Patimokkha, possessed of proper behavior and resort....

...


"On seeing a form with the eye, he does not grasp at any theme or details by which -- if he were to dwell without restraint over the faculty of the eye -- evil, unskillful qualities such as greed or distress might assail him. On hearing a sound with the ear... On smelling an odor with the nose... One tasting a flavor with the tongue... On touching a tactile sensation with the body... On cognizing an idea with the intellect, he does not grasp at any theme or details by which -- if he were to dwell without restraint over the faculty of the intellect -- evil, unskillful qualities such as greed or distress might assail him. Endowed with this noble restraint over the sense faculties, he experiences within himself an unblemished happiness.

"With the abandoning of pleasure and pain -- as with the earlier disappearance of joy and sorrow -- he enters and remains in the fourth Jhana which is beyond pleasure and pain; and purified by equanimity and mindfulness.

"On seeing a form with the eye he does not become greedy for pleasant forms, or averse to disagreeable forms. He abides with mindfulness of the body established and with a immeasurable mind. He knows the deliverance of mind and the deliverance through wisdom as it really is, where unwholesome states cease completely. Having abandoned the path of agreeing and disagreeing, he experiences whatever feeling that arises - pleasant, unpleasant, or neither unpleasant nor pleasant - just as it is. He is not delighted or pleased with those feelings and he does not appropriates them. Interest in those feelings ceases. With the cessation of interest, clinging ceases. With no clinging, there is no becoming; no becoming, no birth; with no birth, there is no old age, sickness or death, no grief, lament, unpleasantness, displeasure or distress. Thus ceases the complete mass of dukkha.

And to elaborate further on this idea of the various forms of sense-consciousness arising ans fading away, let's look at the Loka Sutta:


Samyutta Nikaya XII.44
Loka Sutta
The World
Translated from the Pali by Thanissaro Bhikkhu.
For free distribution only.
Dwelling at Savatthi. There the Blessed One addressed the monks: "I will teach you the origination of the world & the ending of the world. Listen & pay close attention. I will speak."

"As you say, lord," the monks responded to the Blessed One.

The Blessed One said: "And what is the origination of the world? Dependent on the eye & forms there arises eye-consciousness. The meeting of the three is contact. From contact as a requisite condition comes feeling. From feeling as a requisite condition comes craving. From craving as a requisite condition comes clinging/sustenance. From clinging/sustenance as a requisite condition comes becoming. From becoming as a requisite condition comes birth. From birth as a requisite condition, then aging & death, sorrow, lamentation, pain, distress, & despair come into play. This is the origination of the world.

"Dependent on the ear & sounds there arises ear-consciousness. The meeting of the three is contact... [same sequence follows]

Dependent on the nose & aromas there arises nose-consciousness. The meeting of the three is contact...

Dependent on the tongue & flavors there arises tongue-consciousness. The meeting of the three is contact...

Dependent on the body & tactile sensations there arises body-consciousness. The meeting of the three is contact...

Dependent on the intellect & mental qualities there arises intellect-consciousness. The meeting of the three is contact. From contact as a requisite condition comes feeling. From feeling as a requisite condition comes craving. From craving as a requisite condition comes clinging/sustenance. From clinging/sustenance as a requisite condition comes becoming. From becoming as a requisite condition comes birth. From birth as a requisite condition, then aging & death, sorrow, lamentation, pain, distress, & despair come into play. This is the origination of the world.

"And what is the ending of the world? Dependent on the eye & forms there arises eye-consciousness. The meeting of the three is contact. From contact as a requisite condition comes feeling. From feeling as a requisite condition comes craving. Now, from the remainderless cessation & fading away of that very craving comes the cessation of clinging/sustenance. From the cessation of clinging/sustenance comes the cessation of becoming. From the cessation of becoming comes the cessation of birth. From the cessation of birth, then aging & death, sorrow, lamentation, pain, distress, & despair all cease. Such is the cessation of this entire mass of stress & suffering. This is the ending of the world.

See, Koolaid, the Buddha's emphasis in what is occurring in the here-and-now? What all this hinges on -- dukkha or the quenching of dukkha -- is whether one gives in to craving for any particular sensation coming from any particular sensory system. "Consiousness", within this framework, is mere awareness of a sense object arising within the range of a particular sensory system. A noise arises within range of my hearing, and I hear a sound - that is the arising of ear-consciousness. the noise dissipates, and ear-consciousness goes away. If I cling to that sound -- oh, MUSIC! Ah - yes, let's give that a listen, or OH, Damn, the parrot is screaming again! -- then there is clinging to that sensation. If the ceiling fan is running, it might make a constant sound, but i might be completely unaware of that sound, unless it somehow attracts my attention. Ear-consciousness with regard to that sound is absent, because mentally I have tuned that out or I am otherwise unaware of it -- not "conscious" of it.
