When something changes in the outer world, psychic automatism compels us to judge it as bad or good. On the inner level, all changes are potentially helpful. Any judgement is misleading and irrelevant.
Do things change? Well, sort of. In the way a pendulum changes.
If I have learned something and nothing changes, then I haven’t learned anything.
I haven’t changed until there is less of me, until I’ve discarded something.
Change what makes you unhappy or leave what makes you unhappy. Just don’t complain about what makes you unhappy. Complaint is a saboteur, a way of doing nothing while pretending to do something.
