To illustrate the Buddhist approach to the mind, let us compare our body and mind to a computer. In this simile, the body is the hardware and the mind is the software.
As mentioned above, the mind is defined as a non-physical phenomena which perceives, thinks, recognises, experiences and reacts to the environment, not unlike computer software.
Although software needs to be imprinted or registered in something like the hard-drive before it can do anything, in itself, a program represents a lot of thinking by the software manufacturer. Without software (mind), the hardware (body) is just a 'dead thing'. The hardware (body) is of course important in what the computer can do; how fast it is, which programs can be run, and how the computer can interact with the world. However good the hardware is, it can ultimately only perform what the program 'knows'. The hardware can get damaged, or even 'die', and the software can be moved onto another set of hardware; not unlike rebirth!
The software needs to use the 'senses' of the hardware, like the keyboard, the mousea, a video camera, a modem etc. to receive 'input'; just like the mind needs the senses the receive the 'input' of the outside world.
This leads to an important observation: it is easy to recognise that a computer is not 'objective' about the world; depending on what kind of video camera, microphone or modem we connect it to, the input will be different. Similarly, our bodily senses cannot really be objective: people's ears are different, the eyes are different etc., so how can someone ever claim to be an 'objective observer'? Above and beyond that lies the software; the more advanced this is, the more 'intelligent' it will be able to read the world and determine what is the best thing to do. Similarly, the more advanced our mind is, the more intelligent and wise we will be, providing we are not hampered by serious physical problems. As the software actually determines what the hardware does, so is the mind the master of the body - within the physical limitations of the body. But the Buddha made it clear that a human body is the best type of available hardware!
There are limits to the development of the hardware; for example, the amount of electrical circuits on chips is getting larger and larger, but there are physical limits which the developers encounter. With the software, the limit appears to be much less clear; the first types of computers behaved with the intelligence of an on/off switch, but already they can beat a grandmaster at chess and nobody can say where it will end. Similarly, Buddhism teaches that there is no real limit to the development of our mind, and in fact omniscience is possible. At that stage, all our normal values and concepts dissolve as limited and non-objective. Buddhism encourages us to develop the software of our mind to enter into a different state which is beyond limitations, suffering and problems.
The method to develop our mind is summarised as study and meditation. Initially, we need to understand how the programs of our mind work and how they can be improved, and then do the reprogramming in meditation. This is why psychology and meditation are so important.
Below listing of aspects of the mind may appear very dry and boring, but remember, so are computer manuals...
CLEAR-LIGHT MIND
In Tibetan Buddhism, often the so-called 'clear-light mind' is mentioned. This is the most subtle level of mind (see also death & rebirth), which we are normally not even aware of. It appears to the very advanced meditator and during the death process, but in this case, also only advanced meditators will be able to notice it. It is a non-conceptual, 'primordial' state of mind.
From a talk given by HH Dalai Lama. Oct. 11-14, 1991 New York City. Path of Compassion teaching preliminary to Kalachakra:
Question: When people hear of luminosity of clear light that dawns at the moment of death they ask why it is called clear light. What has this got to do with light as we know it?
Dalai Lama:
"I don't think that in the term clear light, light should be taken literally. It is sort of metaphoric. This could have its roots in our terminology of mental will. According to Buddhism, all consciousness or all cognitive mental events are said to be in the nature of clarity and luminosity. So it is from that point of view that the choice of the term light is used. Clear light is the most subtle level of mind, which can be seen as the basis or the source from which eventual experience or realisation of Buddhahood, Buddha's wisdom might come about, therefore it is called clear light. Clear light is a state of mind which becomes fully manifest only as a consequence of certain sequences or stages of dissolution, where the mind becomes devoid of certain types of obscurations, which are again metaphorically described in terms of sun-like, moonlike and darkness. These refer to the earlier three stages of dissolution which are technically called, including the clear light stage, the four empties. At the final stage of dissolution the mind is totally free of all these factors of obscuration. Therefore it is called clear light. Sort of a light. It is also possible to understand the usage of the term clear light in terms of the nature of mind itself. Mind or consciousness is a phenomena which lacks any obstructive quality. It is non-obstructed."
A teaching from Venerable Ajahn Chah (Pra Bhodinyana Thera):
"About this mind... In truth there is nothing really wrong with it. It is intrinsically pure. Within itself it's already peaceful. That the mind is not peaceful these days is because it follows moods. The real mind doesn't have anything to it, it is simply (an aspect of) Nature. It becomes peaceful or agitated because moods deceive it. The untrained mind is stupid. Sense impressions come and trick it into happiness, suffering, gladness and sorrow, but the mind's true nature is none of those things. That gladness or sadness is not the mind, but only a mood coming to deceive us. The untrained mind gets lost and follows these things, it forgets itself. Then we think that it is we who are upset or at ease or whatever.
But really this mind of ours is already unmoving and peaceful... really peaceful! Just like a leaf which is still as long as no wind blows. If a wind comes up the leaf flutters. The fluttering is due to the wind -- the 'fluttering' is due to those sense impressions; the mind follows them. If it doesn't follow them, it doesn't 'flutter.' If we know fully the true nature of sense impressions we will be unmoved.
Our practice is simply to see the Original Mind. So we must train the mind to know those sense impressions, and not get lost in them. To make it peaceful. Just this is the aim of all this difficult practice we put ourselves through."
