Is it possible to achieve universal detachment? How? I have, for some time, tried to detach from things in my life so I can find true happiness without needing anything. Although I have had some success detaching from some things, like the need to be right or material stuff, I still am too attached to some other things, like girls and people that should not be a source of attachment.

I can tell myself I don't need something(and I really don't) but something deep inside still makes it come up on my mind every so often, and mostly together with fear of loss, desire and imaginary situations of both good and bad outcomes.

So my question is about detachment.. how can I practice to be more and more in control of what I feel attachment for, regardless of what it is? It seems that it controls me, and makes me miserable sometimes.. how can I let things go?

Any external object brings pleasurable, painful and neutral sensations1. It is these sensations you have to let go there by letting go of the external object thereby letting go of the roots which create this attachments2. Say you are still reacting to external sensations by you have let gone of external objects your mind still can crave for them.

You are doing this at an intellectual or conceptual level. There are other religions which preached non attachment but inevitably they got attached to the view orr concept of non attachment which would have been more subtle and difficult to eradicate than external attachments.

The way to go is the be able to objectively observe the arising and passing of any sensation from contact. May it be you stay in one posture and want to shuffle around (pain in the old, pleasure in the new posture). May it be sensation just arising. Also thinking caused sensations.

The method to do this is as described in Avijja Pahana Sutta 2 and Pahāna Sutta, whereby cut the source of attachments, through being aware of arising and passing of the sensations in what is felt.

    Then there remains only consciousness,
    purified and cleansed.
    What does one know [cognize]
    with that consciousness?
    One knows, "It is pleasant."
    One knows. "It is painful."
    One knows, "It is neutral."
    On account of a contact that is felt as pleasant, there arises a pleasant feeling.
    When one feels a pleasant feeling one understands, "I feel a pleasant feeling"
    One understands, "With the cessation of that same contact that is felt as pleasant,
    the pleasant feeling conditioned by that contact ceases, it is stilled."On account of a contact that is felt as painful, there arises a painful feeling.
    When one feels a painful feeling one understands, "I feel a painful feeling."
    One understands, "With the cessation of that same contact that is felt as painful, the painful
    feeling conditioned by that contact ceases, it is stilled."
    On account of a contact that is felt as neither pain nor pleasure, there arises a neutral feeling.
    When one feels a neutral feeling one understands, "I feel a neutral feeling."
    One understands, "With the cessation of that same contact that is felt as neither painful nor
    pleasant, the neutral feeling conditioned by that contact ceases, it is stilled."
