We see things and we hear things. We see this world of objects, very beautiful indeed, very attractive oftentimes, and sometimes repulsive also. We hear also of the glories of heaven, the paradise, the Garden of Eden, Indra-Loka. One would wish to go there and enjoy life. That is a desire arising from things heard only and not seen.
Desires also arise from objects seen, which is our practical experience.
When there is an absence of taste for things seen or heard or thought of in the mind, on account of the recognition of the true circumstance of all things in their inter-relationship with the whole universe, desire ceases. One becomes a master. Mastery over the mind is mastery over desires. In a sense, we may say that the mind is only desires. Desires constitute the mind.
