According to Osho, struggling to let go guarantees tension because let-go is never "almost" or in parts; it is a total, effortless yes. Any fragment that holds on cancels the whole. Let-go cannot be achieved by trying; it flowers from clear seeing and understanding. Drop the competitive urge, watch mindfully, and when understanding dawns, surrender happens by itself.
If you try to let go, you’re still holding on; just see clearly and it will happen by itself.
