The Emptiness of the Mind in Kadampa Buddhism

The Kadampa Buddhist definition of Mind is 

"Mind - That which is clarity and cognizes. Mind is clarity because it always lacks form and because it possesses the actual power to perceive objects. Mind cognizes because its function is to know or perceive objects."

Modern Buddhism

In Modern Buddhism Volume 1, p109Geshe Kelsang Gyatso says that as well as understanding how physical things (including our bodies) are empty of inherent existence and ultimately unfindable, we should also understand that the mind is similarly unfindable upon analysis.  

The primary mind is like an empty space that perceives or understands objects. It is not so much a 'thing' as a process, 'an ever-changing continuum' or 'mindstream'. The main cause of the present moment of mind is the previous moment of mind.  

The primary mind of a sentient being is known as the 'root mind', from which all thoughts and other temporary minds (such as minds of anger and attachment) arise, and into which they eventually dissolve.

So the root mind is...
(i) Clear and Formless 

(ii) Cognizing
(iii) Devoid of 'inherent existence' (or any defining essence)
(iv) A process rather than a 'thing'.
Geshe Kelsang recommends meditating on the emptiness of the mind as a means of understanding the emptiness of all phenomena:

"This unfindability is its ultimate nature, or emptiness. We then think: All phenomena that appear to my mind are the nature of my mind. My mind is the nature of emptiness.  In this way we feel that everything dissolves into emptiness. We perceive only the emptiness of all phenomena and we meditate on this emptiness. This way of meditating on emptiness is more profound than the meditation on the emptiness of our body. Gradually our experience of emptiness will become clearer and clearer until finally we gain an undefiled wisdom that directly realizes the emptiness of all phenomena."

When I first read these teachings on emptiness of the mind I was rather puzzled.  Buddhism claims that everything ultimately depends upon the mind, and yet the mind is not findable by analysis.   Surely there must be something fundamental down at rock-bottom on which all phenomena are based?

Then I realised I was slipping into the error of reification - expecting there to be an inherently existing mind.   Looked at logically, the mind can be no more inherently existant than anything else.   The same arguments apply as they do to material things - anything that was permanent and unchangeable could neither act nor be acted upon.   The root mind is not a thing, it is a process, albeit a non-procedural (hence non-physical) process.

Not only is the mind empty of inherent existence, it is also empty of form or structure, though it can cognize forms and structures as internally generated images

In Transform Your Mind  Geshe Kelsang  says   "If the mind is not the brain, nor any other part of the body, what is it? It is a formless continuum that functions to perceive and understand objects. Because the mind is formless, or non-physical, by nature, it is not obstructed by physical objects."

'Cognizing' implies intentionality or 'aboutness'. Physical systems, including machines, are not in themselves 'about' anything. The apparent 'aboutness' of a physical system is projected onto it by the mind of its user.

The lack of inherent existence of the mind means that it has no defining essence, nothing to 'keep it as it is', so it can unobstructedly perceive all objects including those of its own creation. The mind can be 'about' anything whatsoever. This lack of defining essence, combined with lack of structure, allows the mind to change, expand, have freewill, and be creative.

From an article by Kadampa Working Dad:

"...Emptiness greatly increases the effectiveness of our concentration.  We normally grasp at inherently existent objects of Dharma, inherently existent meditating minds and inherently existent meditaters.  If an object of Dharma is inherently existent, then it is actually impossible for a mind to concentrate on it because the object of Dharma is separate from the mind. If a mind is inherently existent, it cannot mix with any object because doing so would change it and inherently existent things are unchangeable.  And if the meditater is inherently existent then they could never benefit from their mind meditating on objects of virtue because there would be no connection between the meditater and their mind.  But when we realize the emptiness of these three, it becomes very easy for our mind, its object and ourselves the meditater to all mix together like water mixes with water.  It was discussed above how mind and its object are like two aspects of the same entity.  We also naturally impute our I onto our mind.  So if the only object of our mind is the object of our meditation (meaning we have perfect concentration) and we naturally impute our I onto our mind (which in this case is the subject/object union) then we literally become our object of meditation.  The meditater, his object and his mind are three different aspects of the same entity.  This reveals an extremely powerful effect of concentration combined with an understanding of emptiness:  we become that which we concentrate on.  If we concentrate on love, we become a loving person; if we concentrate on compassion, we become a compassionate person; if we concentrate on the deity in our Highest Yoga Tantra practice, we become the deity.  If we understand this clearly, we will find it effortless to generate the desire to train in concentration."

A Double-Whammy against the mechanistic model of the mind

The physical,  mechanistic sciences construct their models, predictions and explanations by abstracting and reducing the numerous natural instances of processes operating on structures, into a few generic procedures operating on data.

Hence physical explanations are impossible to construct, will fail, or will be inapplicable as 'category errors' for any phenomena where...

(i) Structures cannot be reduced to data
(ii) Processes cannot be reduced to procedures

The formless nature of the mind gives a double-whammy to any attempts to construct a deterministic physical or mechanistic explanation for the mind.

The first whammy is obvious: something totally lacking in form cannot be expressed as a structure. 

Then there's the second whammy: algorithms and procedures are themselves ultimately structural.  In the Universal Turing machine (to which all other information processing machines are functionally equivalent) the algorithms take the form of state-transition tables, and the Turing machine populates its empty state-transition tables by reading them in from its data tape.

These whammies may explain why The Hard Problem is so hard that it is insoluble by science. The root process of consciousness is not even in principle reducible to a procedural form (it is 'non-algorithmic'). Consequently, attempts at physical or mechanistic explanations are a category error. 

For a discussion of why the mind is a non-physical, fundamental aspect of the universe which is not derived from anything else, see Confronting Materialism and the Delusion of the Mechanistic Mind, and for a clear description of the difference between mind and machine (useful when debating with materialists) see "When the body dies, the 'mechanism' of the body holding the spirit is gone, and the spirit finds a new body sooner or later, perhaps immediately."
