According to Osho, knowledge inevitably changes with time, culture, and a seeker’s conditioning, while realization never changes because it arises only when language, beliefs, and learned frameworks are dropped. After realization, expression (what we call ‘knowledge’) reappears colored by one’s era—Darwin, Marx, or Vedic idioms—so scriptures and teachers sound different. Therefore, don’t cling to words; seek the timeless experience, then let your understanding speak in the living language of the present.
Truth is the same forever, but the way people talk about it changes with their time and what they’ve learned.
