The short answer
Integration is the quiet work after the event. It can mean rest, journalling, therapy, gentle routines, honest conversations and not rushing into life-changing decisions while emotions are still moving.
What responsible support looks like
A responsible retreat should explain what happens after you leave. They should not treat integration as an optional extra or a marketing word. Look for clear aftercare, realistic expectations and encouragement to seek qualified support when needed.
No hurry
Not every experience needs to be decoded immediately. Sometimes the safest thing is sleep, food, walking, kind people and time.
