According to Osho, apply insecurity by recognizing it as a fact, not a mood, and living with clear awareness that nothing—relationships, wealth, health, reputation—is guaranteed. Keep building houses, marrying, working, but drop inner clinging and the illusion of safety. This sober seeing frees you from panic and possessiveness, fosters simplicity, and orients you to present, intelligent action.
See that life is always a bit shaky, so do what you need to do but stop gripping so tightly inside.
