According to Osho, ordinary suicide is an escapist, negative use of will; it isn’t real resolve. By fleeing life’s ‘exam,’ the person gains nothing spiritually and is reborn with a weaker, more impotent soul, having missed the chance to awaken willpower. Only a slow, conscious death-as-discipline (like Jain fasting) can strengthen will; instant self-destruction cannot.
Taking your life out of despair makes you return weaker, while only a brave, mindful facing of death can grow inner strength.
