Desire is a curvature of inner space, but inner space varies in its flexibility, capacity and dimensionality. You don't know where desires come from they are not transparent to self-awareness, and yet self-awareness inhabits them completely. Some motivations are felt as if they are alien visitors, others are so natural-seeming that you never think to question them. Some you surrender to others you worship. Curvatures arise, force without motion, tension and directedness, the drawing of things into a specific relation independent of thought. Inner space arises with desire, you don't know it unless it is curved, yet it is what you find yourself in. It is because you think that there is a single mechanism for all desires, the person being what makes it all hang together. You don't know you exist until there is something you want. What you think you are is the inner space in which you are. This is imaginary and yet it fills lifetimes. Everyone is so motivated, you find yourself in a world of complex motivations, a system. Whatever you can't see is hidden. Everyone is a question, their wants distort the space already curved. Your desires are not independent they are only the curvature of the space in which you think you are and which is actually what you are - the imaginary tensor of imaginary space.
