Imprinting is a topic I am still exploring, but the essence is that our electromagnetic self can become shaped and disrupted by certain experiences and decisions, such that we become 'stuck' in those limited and un-natural patterns until we understand how to clear them and go ahead to do that. Clearing imprints requires a combination of emotional expression and changes of thinking.
