The Four Agreements is a spiritual self-help book by Don Miguel Ruiz, first published in 1997. Drawing on ancient Toltec wisdom, the book presents four simple yet powerful principles intended to help individuals achieve personal freedom and inner peace.

The four agreements are: be impeccable with your word, don’t take anything personally, don’t make assumptions, and always do your best. Ruiz explains how adopting these agreements can help break limiting beliefs, reduce suffering, and improve relationships. Written in a clear and accessible style, the book blends spiritual insight with practical guidance, encouraging readers to transform their mindset and live with greater authenticity and awareness.
