I have no problem with the injunction to let go of attachments. I completely agree with doing that. However, what you are calling attachment is not attachment. It is acknowledging our normal human psychological and emotional construction which evolution has provided us for our survival. As we learn to grow into maturity, we learn to work with our bodies, not deny them. Denialism, is itself a form of attachment. It is attached to an idea that being human is bad, and that only escaping our human nature will bring us peace. That is unhealthy, and does not lead to spiritual transformation at all. True spirituality is an integration of all the parts of us, but in harmonious and healthy ways. We don't deny our bodies. We awaken them. Once awakened, we realize they serve us, rather than are our enemies, which you make them out to be, it appears.
I have also even heard some Buddhists call
love an attachment. That is not only unwise, it is unreal. It is a delusion and a form of attachment itself. Now please note I said "some", not all. It's no different in Buddhism than it is in Christianity where people take Wisdom teachings, literalize them, turn them into attachments, and teach others their incorrect, unenlightened misunderstandings of higher teachings. It's not specific to religion, but to how people lacking context literalize these things and distort their meanings. The Buddha became enlightened after he ate food, not while he was starving himself to death.
Attachments come about when we look to these things as the ultimate source of our happiness. So yes, we can be attached to the natural, normal and healthy things too. But saying those things is what is attachment, is form of self-deception. It what we
do with them, where the attachment lies. Not with the thing itself. To imagine if you can "get rid of anger" is the key to your awakening, is still attachment. You assume that only if this thing were changed, then you can be free. Rather, we seek to be Free itself, and then everything is manageable and nothing is "unclean" in itself. Anger, can be transformed into "fierce compassion", for instance. If you think anger is a sin, or an "attachment", tell that to mama bear protecting her cubs.
I have no problem with learning healthy anger management. But to make anger the enemy, versus your personal lack of control with it as the actual problem, is a form of subtle self-deception, a "near enemy". You make it about the anger itself, rather than how you deal with natural, normal, and healthy human emotions. Anger exists for an evolutionary purpose, just like our bones, just like our lungs, just like our feet. It's not a mistake. What we do with it, how we hold it, makes it that. To call sex evil for instance, as many spiritual escape artists try to say, externalizes what is actually a shortcoming of avoiding facing the truth about ourselves and our own personal attachments with normal things.
To make any of these things the enemy, empowers them in our lives by energizing them with negative attachments from our minds. Facing the truth of ourselves and our responsibility with what has been given us by nature, is what actually sets us free, experience teaches me. Making these things the enemy, is a near-enemy form of attachment.
I hope you take the time to read and consider these things.
