The nature of the object of the attachment doesn't matter. It's the attachment itself that is at issue, and that attachment is in essence identification with mind.
(Edit: at the end of this I will clarify what I mean by mind, intelligence. We may be using words in different ways)
Two Things:
First, the object of attachment
does matter. If it was otherwise, the acts of self destructive/entanglement/ignorance would be indistinguishable from acts of liberation/freedom/wisdom. For one whose glossary (ie, mind) is bereft of any liberating acts, then I guess the best one can do is attempt to refrain from everything. Hopefully this may lead to a broader perspective at some point, but unless it culminates in the mind adopting liberating activities, one will be stuck with the problem of a mind running to nonsense.
And second, once again, we are left to ponder whether the mind is ultimately false or whether it is a reflection of something substantial. If it is false, then by all means, attempt to do head stands 24 hrs per day and send the mind to the fartherest reaches of oblivion (however the mind will kick and drag you screaming every inch of the way).
Actually many people adopt such acts simply as diversions to prevent themselves getting jaded by their attachments. In otherwords, meditation is all about doing it "for a change", rather than "for change", if you catch my drift.
However, rather than an all out illusion, if it is a reflection, then that means the mind must have some core information that is actually accurate. So one can work to have a purified mind (and a purified mind gives rise to purified action).
It is kind of like acquiring a cup of pure water. If you have a cup of impure water, you already have a cup of pure water .... the only problem is that you have to find a way to get rid of all the impure parts. Its not that you just throw it away.
In the same way we have to find a way to purify our mind, and not merely throw it away.
It takes effort to reinforce this illusion, to be embedded in a culture that calls you by name or asks who you are and what you want. I don't know that there is any effort which can break this, but sometimes it disappears (perhaps by lack of effort to maintain it), and in it's absence there is the freedom I speak of.
The problem is that this freedom is not sustainable .... or to go back to the cup of im/pure water, if you merely throw it away, you will get thirsty (and then, who knows what you will drink ...).
In the same way, if one attempts to wholesale throw away material existence, while it may afford the opportunity for a broader perspective, one will simply come back for round two, and so on.
No, the brain is not the mind. You probably have a mind that forms connections and creates thoughts in response to sensory input, but it is not primary. The brain is primary and can't observe itself. It feels very strange if it should ever happen to you, but it is possible for the mind's illusory center of activity to take a back seat. One's actions then seem to happen spontaneously, even surprisingly, without thinking. If you take away anything from this discussion, it should be hope that this is possible, although I have no idea how it's done, it happened to me quite by accident. Then you realize that what you thought was you, your mind, is only a secondary sub-system of the brain. It can be noticed but ignored, it's not as important as you might think. Using the mind to control the brain and the body creates uncomfortable feedback loops, useless introspection, tension, fear, and excess thought. In other words, suffering.
By mind, I mean that aspect that likes and dislikes things. The senses feed the mind information, according to our 5 senses, and the mind decides whether we like it or not. By intelligence I mean that aspect that perceives benefit, and thus either accepts or rejects something. So for instance our mind may not like the taste of a particular food, but we may eat it on the strength of intelligence, since we know it is good for us. Or alternatively, our intelligence may get hijacked by our mind, and we may eat something that tastes good even though we know it is bad for us. In this way, we are internally conflicted by this battle between the mind and intelligence. The senses pump us full of information about what's available and, between the mind and intelligence, we engineer a narrative born of pleasure and suffering and acceptance and rejection. This narrative ultimately writes itself according to our pursuit of benefit.
In a perfect world, we have a mind that naturally delights in things that bestow (actual) benefit. However, if we simply try to bludgeon our mind into obedience via intelligence or if we simply let our mind run riot over our intelligence, there is a good chance we will die prematurely..
In short, to be successful, we have to have all parts of our inner world come together in an appropriately cooperative fashion. Obviously this is not such an easy thing and takes time. If we don't, we will be conflicted, regretful, depressed, fearful, etc.
A cruel irony of modern life is that there is an overt focus on feeling good, rather than acting good. The result is simply inner conflict.
