According to Osho, the question is misguided: don't dissect thought - drop it. Thought's structure is like dreams: illusory patterns. Instead of psychoanalyzing, awaken from it. Become silent, sink beneath the waves of thinking, and they vanish; at your depth there is no thought, no dream. What is needed is a wake-up shock - alert awareness - not intellectual mapping.
Don't study how thoughts work; just wake up, get quiet inside, and they fade, leaving clear awareness.
