According to Osho, fatigue does not mean a lack of energy; in fact, energy is awakening. What’s getting tired are the senses—the doors through which energy flows—not the energy itself. Exhaustion arises from identifying with these doors. Remember you are the awareness within; let the tired senses rest, turn inward, and allow the rising energy to stabilize without forcing outward activity.
Feeling tired usually means your senses are worn out, not that your inner energy is gone—rest them and stay quietly aware inside.
