What changes is the mindset from which he is seeing life. Sometimes, it is higher. Sometimes, it is lower. When it is higher, he is more strongly confident in his attachment to you. When it is lower, he gets pulled by all the offerings of the ego and the people in his life who share those values with him. He doesn’t know that he is constantly gravitating between the two. Otherwise, it would be easy to fix, and it is not. One has to learn to recognise both mindsets and understand the consequences of each.
