i don't think there is such a thing as desire free for the spiritual aspirant.
i think there are things of value to desire... practicing mindfulness and compassion.
the desire to be healthy and beneficial to the planet.
Desire is a condition of disturbance and unrest of thoughts and feelings.... Only meditation yields this ever-increasing ever-new responding joy. Sooner or later you will realize that you want a thing only until you get it. Then you will start looking for something else. But in discovering soul joy, you will find that "something else" which you were seeking through the labyrinth maze of desires for false pleasures. You will never tire of this ever new joy of your soul which is of God -- Paramahansa Yogananda
It is not bad to 'want' somethings but is wise to remember that; 'Only the inner effort of meditation brings proof of the existence of joy unending.' P.Y. 'You will tire of everything else but that joy.' P.Y.
