What's the answer to this Buddhist koan (story)?

The emperor lost in that second on the hill his sense of self, he was nothing and at the same time everything. A moment of connectedness with everything. It happened to me when I was 25 , I am now 45 but it has stayed with me all my life. Its almost impossible to put into words so I don't , mine experience was with nature, dragonflys to be truthful but the effects were the same as the desert. 'No self'
