How are living beings conscious? (WHP)

"Consciousness" is one of the Five Groups [that comprise] Existence (Five Aggregates of Clinging). It is one of the Four Nutriments. It is the third link of the causal chain on the arising of suffering called Dependent Origination. It is the fifth in the sixfold division of elements.

Viewed as one of the Five Aggregates [trillions of discrete phenomena lumped into five groups or categories], it is inseparably linked with the three other mental aggregates (feeling, perception, and formations) and furnishes the bare cognition of the object, while the other three contribute more specific functions.

Its moral and karmic character, and its greater or lesser degree of intensity and clarity, are chiefly determined by the mental formations associated with it (particularly the most salient formation, "volition" or cetana, which determines if a karmic act is beneficial, unwholesome, or neutral).

 

Just like the other aggregates or "groups of existence," consciousness is not so much a thing as a flux (sotā, a "stream of consciousness") and does not constitute an abiding mind-substance. 

Free your mind. Rest will follow.

Nor is it in any way a transmigrating soul, entity, or abiding self, even though it is commonly regarded as such by ordinary uninstructed worldlings not yet freed of ignorance regarding existence. Arhats, the noble ones, who gain knowledge and vision recognize it for what it is and are freed of suffering, which is called enlightenment, the realization of nirvana, "the end of all suffering").

The Three Marks or Characteristics of Existence (the impermanent, unsatisfactory/disappointing/woeful, and impersonal nature of all conditioned phenomena) are frequently applied to consciousness in the texts (e.g., in the Anattalakkhana Sutra, S.XXII, 59).

The physical base of the "mind" is the heart (K)

The Buddha often stresses that "apart from conditions, there is no arising of consciousness" (MN 38). And all of these statements about its nature hold good for the entire range of consciousness -- be it "past, future, or presently arisen, gross or subtle, in oneself or another, that is, internal or external, inferior or lofty, far or near" (S. XXII, 59).

  

Six consciousnesses

The seven main chakras,energy centers, along the spine (Manifesto-Meditations)

 
According to the six senses it divides into six kinds: eye- (or visual), ear- (auditory), nose- (olfactory), tongue- (gustatory), body- (tangible), mind- (mental, intuitive, memory, psychic) consciousness. 

 

About the dependent origination or arising of these six kinds of consciousness, the Path of Purification (Vis.M. XV, 39) says: 

• "Conditioned through the [sense base or sensitive portion within the] eye, the visible object, light, and attention, eye-consciousness arises.
• Conditioned through the ear, the audible object, the ear-passage, and attention, ear-consciousness arises.
• Conditioned, through the nose, the olfactive object, air, and attention, nose-consciousness arises.
• Conditioned through the tongue, the gustative object, humidity, and attention, tongue-consciousness arises.
• Conditioned through the body, bodily impression, the earth-element [the solid quality of materiality or rupa], and attention, body-consciousness arises.
• Conditioned through the subconscious [or default, underlying] mind (bhavanga-mano [manas, mind]), the mind-object, and attention, mind-consciousness arises."

The Abhidharma literature distinguishes 89 classes of consciousness as being either karmically wholesome (skillful), unwholesome (unskillful), or neutral, and belonging either to the Sensual Sphere, the Fine-Material Sphere, or the Immaterial Sphere, or to supermundane consciousness. See Table I for the detailed classification.

What is mind? What is consciousness?

Amber Larson and Dhr. Seven, Wisdom Quarterly (COMMENTARY)

No one has to lose his or her head wondering where "mind" is (MaretH/flickr.com)

The brain starts at the base of the spine

Does Buddhism have an answer? The Dharmic religions are very interested in "mind," which is roughly the equivalent of heart, the seat of consciousness. We think the brain is the mind, but it is not. The base of physical base of consciousness was not spelled out by the Buddha precisely the way the other senses were. Buddhism acknowledges six senses, mind being the sixth.

 

Mike, a living headless chicken (MTHC)

But it is pretty certain, and individually verifiable, that the "mind door" is near the are of the physical heart not up in the head. If anyone considers the matter for a moment, it becomes obvious that the entire body is conscious -- informed by a gut feeling, a broken heart, a mild headache, a strange tingling feeling, and so on -- all playing a part in what we are conscious of at any moment and what we feel about it; "thought" is a minor part.

A powerful placebo

For example, few people have been told that there are many neurons -- "brain" cells -- in the lining of the gut and in the heart. But we walk around all "scientifically minded" thinking neurons are somehow exclusive to the brain, up in the head, limited to the cranium. Neurons, ganglia, axons, and all that hardware extends down the brainstem into the spine innervating every part of the conscious body. We don't need a brain to live; a brainstem is enough -- ask anyone with microencephaly. We sure do need a heart. Some cruel/greedy humans chop off the head of chickens to sell their bodies and are surprised that they live on. Ask Mike, you know, Mike the Headless Chicken.

I'm not a monkey! My doctor takes them, too!

We are all taught, mostly by long winded drug commercials that depression, anxiety, and other mood disorders are due to "imbalances" in our neurotransmitters (actually, that's at least as much of an effect as a cause in the feedback loop of the body), but what we are rarely if ever told is that most of these transmitters are in other parts of the body. Case in point, if one has a section of the colon removed for whatever reason, one is almost certain to come down with severe clinical depression. Yet, look how we treat our beautiful colons. Why would that be? It's the brain in the gut, the brain in the heart, the brain in the glands -- the rolled up gut, which is 23 feet long, has a lot of braincells.

However, of all the sages of India and Vedic Indus Valley Civilization, no one went further in detailing the "mind," consciousness, software, mental processes, and mental concomitants (cittas and cetasikas) than the Buddha. It is what the entire Abhidharma (the "Higher or Ultimate Teachings") is about -- one third of the Dharma alongside the conventional sutras and the monastic disciplinary code.
 

Mind is more complicated than a clock.

So what is "monkey mind"? Try to meditate and you, too, will find out in about a minute. But, first of all, What is MIND?

The individual (let's say the gandhabba or Sanskrit gandharva) is body and mind, the physical-psychological process of becoming, of phenomenal conditioned-existence, the world, the process of perception. The Buddha outlined this as a conglomeration of eight impersonal heaps called the Five Aggregates. (I thought you said eight? Yes, the first four are collapsed into one category simply called "form").

"Mind" in Buddhism is defined as the remaining four categories: feelings, perceptions, formations, and consciousnesses (viññāna). All of these are plural because they are heaps, aggregates, countless discrete units within each category, always changing, always impersonal, always unsatisfactory.

• The Abhidharma distinguishes 89 classes of consciousness

Clinging -- to ego, notions of self, soul, eternal existence, selfishness, possessions, likes and dislikes, strong preferences, sensual pleasures, and so on -- occurs because of this illusory separate "being" or personality which arises dependent on causes and conditions, nutriments. What are the causes and conditions? They are explained in the meditation on Dependent Origination as 12 causal links to be contemplated, penetrated, and experienced for liberation.

Shut up, monkeys are cool! - the Beebs

Traditionally, in Buddhist instruction, early teachers noted that just as a monkey going wild in a tree grasps one branch and before letting go of it is grasping at another so, too, the meditator barely gets done with one line of thought and s/he's onto another. This is called discursive thinking, a great impediment to calm and insight IF we identify with it. Just let it be. There is no reason to try to stop it; it is usually enough to detach enough by becoming an observer. It really is ridiculous and like a chattering, clambering, confused monkey, full of frenzy, restless, and craving constant stimulation and/or entertainment.
