According to Osho, a 'complex' is not a real obstruction but a thought-induced illusion; it appears when mind meddles with life. Therefore no sadhana is needed—stop believing the borrowed ideas and theories, drop overanalysis, and return to simple awareness and spontaneous living. By seeing the idea as false and acting directly, the complex evaporates, like the wasp flying once it ignores the book.
Like the wasp, stop believing the scary idea and just do the thing—then the ‘problem’ vanishes.
