The greatest demonic cultivator, He Huan, split his divine consciousness into two right before going into tribulation and created another self; whom he named He Ku.

He Huan reached enlightenment, and from demonic cultivation entered into Buddhism; reaching the state of Nirvana (leaving no room for self in one's heart), but who knew that against all reason He Ku remained in his heart and didn't have the intention to leave.

Forget it, it wasn't his fault for not having self-harming tendencies and therefore reluctant to lose his other self. Since this was the case, then this road of Buddhism, he won't take it.

Is there a problem with people loving themselves? Of course not.
