A period,
not a session.
Integration is the ongoing relationship between what happened and how someone actually lives.
It is not a stage that begins when the acute effects end and finishes when the conversation does. Whether an insight becomes anything durable is settled over weeks and months, in sleep, relationships, work and ordinary habits — not in the hours afterwards, and not by how remarkable the experience felt at the time.
Whether an intense experience predicts lasting improvement in how someone functions is an open question in the research, not a settled finding. Teaching models that promise a particular speed of transformation are proposing something, not reporting it.
