The Buddha wanted him to love the world, but he could not tolerate him loving an ordinary woman.
The world is safe and secure, and I will live up to the Tathagata and your Majesty.
He was originally a prodigal son in the world, talented and rebellious. But he was imprisoned in the Potala Palace for life. 253 "Bhikkhu Precepts" tightly bound his soul.
Of course he wanted to escape, he wanted to find his "Maggie Ami", the moon-like person. To hell with all the rules and regulations!
From then on, there was no living Buddha "Tsangyang Gyatso" in the world, only the prodigal son "Dang Sang Wangbo".
