According to Osho, spiritual youth is not about age but an inner freshness—the courage to challenge the past, embrace the new, and hear the call of sannyas. Where society worships the dead and the old, youthfulness withers; awakening needs springlike energy, trust, and celebration. True sannyas is aliveness, not respectable deadness.
Being truly young means staying open, brave, and alive enough to try something new inside, so you can hear and follow the call to wake up.
