Humanity is one organism. The earth is. And the cosmos is too.
The brain, which can indulge in its fantasies and not feel how the arms, the legs, the heart, the lungs and all the other organs are working and consuming pain, can be described as completely unconscious and out of touch with reality.
Liberation serves the whole cosmos. Those who see themselves detached from it, and then still in a fairly good position, cannot understand it.
