[Summary] Richard Schwartz's book, Introduction to the Internal Family Systems Model, introduces the foundations of IFS therapy. IFS posits that the mind is comprised of various ‘parts,’ including protective parts (managers and firefighters) and vulnerable parts (exiles). This therapy model aims to help individuals access their ‘Self,’ a core of inherent goodness and wisdom, to foster healthier internal relationships between these parts. The book details how these parts interact, explains how to identify them, and offers exercises to facilitate self-exploration and healing. Ultimately, the goal is to achieve self-leadership, improving both internal harmony and external relationships.
