I believe, though I may be incorrect, that they come when called to help in the meditative state, and leave thereafter. As one has the higher self and three angels (guides) also with them at all times, there is no real need for Q'uo to remain. What their presence does is increase the vibration in ones vicinity so it is easier to align oneself with the higher vibration, thus aiding in the meditative state.
