According to Osho, when the mind is soaked in negative thoughts it becomes a fog that distorts reality, drains vital energy, and manufactures a private hell. Identification with these thoughts tightens the ego and attracts more of the same, forming a vicious circle. Awareness is eclipsed—you stop seeing what is and simply recycle inner poison through perception, feeling, and action.
Negative thoughts are like dirty glasses that make everything look bad, so you feel worse and keep finding more bad.
