Many spiritual texts claim that the enlightened have no desire. They even cite examples of enlightened individuals who have to be force fed because they have no desire for food. They have to be tended to carefully because otherwise they may wander off into the jungle or be indifferent to worms boring holes through their legs. You may wonder if that is really true and if so, what is actually going on there. Let’s take a look at the mechanics involved.
The human nervous system has evolved sufficiently to hold within its awareness the full spectrum of the grandeur of existence, including direct awareness of that one thing that is the source of all things, pure Consciousness, pure Is-ness, the Transcendent, the unified field of physics. That level is the essence of everything, the source of everything. It cannot desire anything because it already is that thing.
However, full enlightenment is an integrated state, where the individual can function in harmony with all levels of existence. Harmony on the physical level certainly includes tending to and caring for the physical body.
In the state of full enlightenment, a person is then awake to that level of their being that is free of desire, while simultaneously functioning in the world of desire, the world of wanting. So even while it is true that an enlightened individual is free from desire on the deepest level of their being, they simultaneously have desires on more superficial levels.
