The strength to stand back up after hitting the bottom. The strength to climb up out of the pit. The ability to allow the light from your eyes to return so you can see through the darkness.
It is not a stripping down, it is their way of showing you who you really are.
There is an old Japanese (?) proverb ‘Fall down seven, stand up eight’. No matter which pantheon you follow, the gods will show you your true self.
