According to Osho, you feel happy because you can understand my words; you cannot yet understand silence, which requires your own silence. You feel sad because my speaking is unpredictable and may disturb your beliefs; I keep moving, not offering fixed catechisms. Mixed feelings arise from enjoying the familiar while fearing transformation; courage and inner silence resolve the tension.
You like the words you can follow, but you fear they’ll shake your beliefs; be quiet inside and brave enough to change.
