You're trying to integrate your professional life with your personal life. You read books about it. You do exercises. You try to bring more of yourself to work. You try to leave work at the door when you come home. The integration is a project. Years pass. You're still oscillating. The integration never lands. The project, by definition, has no end state. Projects can't produce what integration is.
K had a different relationship to integration. He saw integration not as a project but as a residue. When the fragmentation is seen through, integration is what's left. Nothing has been combined. Nothing has been integrated. The two sides that were supposed to be integrated were seen to have been one thing, fragmented by thought. Drop the fragmentation. The integration that was always there shows up.
Project-based integration treats the inner and outer as two real things needing to be combined. K's view: there was always one field. The inner-outer split was a thought-product. The split is the disease. Integration is what happens when the split is seen as a thought-product. Not work. Just seeing. The work was what kept the split alive. The project of integration was the daily renewal of the very division it was supposed to heal.
The body of someone in a project of integration is striving. The body of someone who has seen through the fragmentation is at rest. Integration was supposed to be the second body. The project was producing the first body. The two states feel different in the chest. Project-integration is forward-leaning. Residue-integration is upright, without tension.
You don't combine the inner and the outer. You see they were never separate. What's left is the integration. The project of integration was the fragmentation, dressed up as the cure. K wanted the seeing, not the project. The seeing takes a moment. The project takes a lifetime and doesn't arrive.
