...problems within your self-relationship.
How you relate to yourself is how you relate to everyone and everything.
How you do anything is how you do everything.
A question to ponder: What does this relationship challenge I'm facing reveal in my relationship with myself?
Seeing how you're complicit in the challenges you're facing is the first step in surrendering your attachments to them.
"Relationship is the mirror in which the self is revealed." Jiddu Krishnamurti
