We Do Not Know What People Are Carrying

During my training as a Psycho-Spiritual Therapist a client I was guiding lead us (me and him) to a place in his subconscious mind where he was a child fleeing Nazi guards during the Holocaust, and he left younger siblings behind who could not make the escape. He remembers running and leaving them.

This subconscious (past-life?) narrative was woven into his life beliefs, thoughts, and ways of being.

What do we know about what another human is carrying with them?
What do we know.
Lets be compassionate to one another.
