She took a pilgrimage or journey that has moral importance to beliefs and faith. Pilgrimage is a common human experience and many religions recommend pilgrimages as an OUTWARD search.
She taught the challenge of stilling your mind which applies to everyone, whether you pray to Christ, or some other higher power, or simply meditate. The book teaches that prayer/meditation brings peace and renewed joy in life and relationships. An INWARD search.
I thought the book offered insights into the process of learning to forgive yourself and others.
She also learned that the nature of God is love. And, the book teaches faith and devotion.
The takeaway is:
search for truth by distancing yourself from everyday circumstances
begin/continue to pray . . . then stop and be quiet and listen
forgive yourself and others
know that God is love
have faith in what you believe is true
