According to Osho, sadness feels more real because it is authentically yours, arising from your own aloneness, while most happiness is borrowed—dependent on people and situations—so it remains thin, mixed with hidden hate and fear of dependence. Rather than escaping it, meet sadness in silent witnessing; it becomes a doorway to meditation, rest, and the discovery of your eternal aloneness, renewing you.
Sadness is real because it comes from you, while happiness often depends on others—so sit with sadness and learn from it.
