According to Osho, Bokoju’s “pre-arrangement” was not against tathata. He did not pre-plan; he simply allowed what was arising to flower, acting without the sense of a doer. In tathata, even arranging is natural if it comes spontaneously; calculation and concern for propriety would be ego. The true criterion is inner suchness, not outer appearances.
Like a flower opening by itself, his actions came naturally without ego, so they fit tathata; forcing or calculating would have been against it.
