Question: There seems to be the assumption there that the idea of being able to place attention is somehow mistaken. How would one know this? Attention moves. Are we moving it, or is something else moving it?
We can certainly place attention here or there. But as your questions indicate this needs to be analysed.
The Abhidhamma holds that there is absolutely no self, there are only conditioned and conditioning elements. “We”, “self”, “agent” are only concepts with no reality. There is of course nothing wrong with concepts.
The issue is that is that we instinctively hold these concepts as having characteristics that they don’t possess: We think they have actual existence. This wrong perception goes far deeper than language, culture or education - it is what drives samsara.
Thus when placing attention somewhere - or indeed doing any action- underlying the action is often the view that at some level believes “I am doing” so, or merely instinctive activity rooted in ignorance of the nature of actual reality.
In fact there are many different conditioned realities that are present when placing attention and the teachings are the necessary guide to help us understand this.
As an example the Satipatthana sutta commentary explains the action of looking:
Within, it is said, there certainly is no self or soul which looks straight on or looks away from the front. Still, at the arising of the thought ‘I shall look straight on,’ and
with that thought the process of oscillation (vayo dhatu) originating from mind, [citta samutthana] bringing into being bodily expression [viññatti] arises. Thus owing to the diffusion of the process of oscillation born of mental activity, the lower eyelid goes down and the upper eyelid goes up. Surely there is no one who opens with a contrivance.
Thereupon, eye-consciousness arises fulfilling the function of sight, it is said. Clear comprehension of this kind here is indeed called the clear comprehension of non-delusion. Further, clear comprehension of nondelusion should be also understood, here, through accurate knowledge of the root, through the casual state and through the temporary state
Visuddhimagga
The absence of interestedness on the part of ignorance, such as ‘Formations [sankhara ] must be made to occur by me, or on the part of formations, such as ‘vinnana
must be made to occur by us’. One who sees this rightly abandons self view by understanding the absence of a maker. xvii 312
Cariyapitaka atthakatthaa, translated by Bhikhu Bodhi (p. 271 ) in Net of Views.
…And: 'When there is patience, the mind becomes concentrated, all formations appear to reflection as impermanent and suffering; all dhammas as not-self, nibbana as unconditioned, deathless, peaceful, and sublime, and the Buddha-qualities as endowed with inconceivable and immeasurable potency. Then established in acquiescence in conformity, the groundlessness of all ‘I-making’ and ‘mine-making’ becomes evident to reflection thus: ‘Mere dhammas alone exist, devoid of self or of anything pertaining to a self. They arise and pass away in accordance with their conditions. They do not come from anywhere, they do not go anywhere, they are not established anywhere. There is no agency in anything whatsoever.’.
This understanding, while still only at the intellectual level, helps to dispel wrong view at the gross level and that is a prerequisite for deeper understanding, as I understand the way.
