According to Osho, everything is natural — both the wave of thoughts and the wave of no-thought. Silence is not a violation of nature but one of its spontaneous movements. Stop dividing experience into 'natural' and 'unnatural'; simply witness whatever arises. By relaxing this judgment, you align with the whole and allow effortless clarity to unfold.
Yes—having no thoughts is as natural as having them; just let it be.
