I practice Secure Detachment.
For me, detachment is not about being desireless or divorced from the world and others, it's about being aware of and in relationship with reality and the world.
I have egoic desires--I desire to have a thing, to go to a place, to be with a person. All day I have these desires, and I mostly just completely indulge them. Egoic is not a swear word, it's just an awareness of self-interest and preference. I have every right to pursue my preference. My life is for me. My body is for me. My experiences are for me.
And, in right relationship with reality and the world, I pursue my preference with abandon. That is, I abandon the idea that my preference is correct or righteous, or that violations of my preferences are evidence of something going wrong in the world. I pursue my preference simply--it's just what I want to do. I'm always doing something!
My preferences are sacred to and for me, and I have every right to use my time, energy, and attention in ways I prefer at all times.
AND it is correct and true and simply reality that the world does not conform to my preferences, that I will not be given my way, that in thousands of ways each day my preferences will be violated and this is a feature of reality, not a bug. I can have the right to have what I desire and not the ability to have it! This is simply a truth in the world.
I am detached from the outcomes of my egoic desires, because that is part of who I want to be. Who I want to be--that is the authentic desire which ideally gives rise to the forms of my egoic desires, if all's in integrity.
Who I want to be in the world is my deeper desire, and it applies as I receive my egoic desires and as I perceive myself deprived of those egoic desires. Who do I want to be while I get what I want? Who do I want to be while I don't get what I want?
Who do I want to be in this world which has so much to offer, so much that is inside my preferences and SO MUCH MORE that is outside my preferences? Who do I want to be in this world which was not designed for me, but is habitable and maybe even enjoyable, to the extent that I curate it?
