We can let go of desire, via experiencing them in the mind’s mental space. If as per the positioning on the human social hierarchy and the place in life where we find ourselves at, if trying to acquire the needs actually is too time expensive, it’s better to experience them in the mind & then let go and more on, move forward.
This can be a very strong, powerful, efficiency technique. Experiencing the fulfilment of our desires in the mind which has zero external time/money costs, can be used to attain many such unattained desires in order to overcome them and move forward.
