According to Osho, merely cultivating endurance toward difficulties often collapses into resignation if it arises from an unripe, weak ego. Forcing egolessness strengthens the ego in subtler ways. First ripen—become centered, integrated, strong by fully engaging life—then surrender happens naturally. Like a rich man freely becoming poor, true letting go in meditation comes after 'enoughness,' not from premature stoicism.
If you grit your teeth and “endure” before you’re strong inside, you just give up; grow fully first, then letting go is easy and real.
