The universe seems to function adequately enough without the need of desire.
If inquiry is done on the word desire it cannot be found. It is a word that forms part of the illusion of separation. Its like building a brick wall within a dream. When the waking state is reached then the wall is nowhere to be seen, all that effort seems to have been wasted. Maybe your dream muscles ache, but your waking muscles show no such discomfort.
Desire contains within it the seed of its own destruction and with it the destruction of the illusion. Yet the illusion persists and so it must be utilised. The dream tools are required to end the dream.
Recognising that a desire is required in order to have less or more desire really shows it for what it is. How large is the quantity of desire needed to reduce desire to zero ?
if everything requires desire then what is necessary for desire ?
gets weird doesn't it ?
Self inquiry can show that desire does not exist or persist. This can be very uncomfortable if there isn't a degree of stillness present. It can be destabilising in a particularly unpleasant way.
All the talk of doing something, going somewhere, quitting practices, increasing practices can be seen through the lie that desire exists in any sense at all. Yet here we are and this is what we must do.
In the dream sense then do X to wake up. Desire will be necessary because it is part of the rules of the game. These rules can be used as levers. Maybe in a dream a ladder is built to escape the dream. The ladder cannot ever break the dream boundary but the act of attempting to do so fuelled by desire will create the circumstances by which it can be realised. We don't employ any such mechanism within a dream state, we don't do practices or self inquiry and yet we wake quite naturally from it. We didn't hit a lever, walk through a door, work on becoming aware or enlightened.
