"Having God as a friend," living in friendship with Jesus - this was the charisma of Saint Teresa of Avila. It is also her spiritual legacy. Through inner prayer, this friendship became increasingly the focal point of her entire life. The present exercises invite participants to follow in Teresa's footsteps for a period of 40 days, progressing step by step on the path to friendship with God and Jesus. The exercises can be conducted both individually and in groups and are always structured in the same way. After the daily theme is introduced, there are moments of preparation, prompts for reflection and meditation, scripture, and prayer, as well as a daily inspiration.
