Detachment refers to a state of being where you are void of earthly desires and or of any earthly “goodies”. You remain in a state of complete satiation at all times and everywhere, in this time-space reality which we call human existence. However, when you are in concurrence with the fact that you are a formless spirit now temporarily residing in this “body”, you will also agree that you are eternal. Being an eternal spirit, the “larger “part of you is formless. The formless spirit you, unbridled by space or time has no need or desire for any material needs or human desires. And that in a nutshell is detachment.
So, when you yearn for “spirituality and well-being”, in this time-space reality, you will naturally yearn less for earthly “goodies” and all human desires. This state of well-being through the path of spirituality will see you shed all ego and greed. Both ego and greed are innate characteristics/elements that we are born with and into, in this time-space reality. This ego and greed is further fueled by the environment we grow up in, by our parents, school, workplace, and social circles. This ego and greed become a vicious cycle that blurs or even blacks-out all spirituality and well-being.
So, to pursue a path of spirituality and well-being you really need to first shed all ego and greed along with all other earthly desires. This does not mean, living like a hermit. But to ease out of all earthly desires, ego, and greed. And when you have attained a state of detachment, you will naturally be in a state of spirituality and well-being. Implying quite simply, that you cannot attain spirituality and well-being without first detaching from all things earthly.
