The Spiritual Direction.
“Only that mind which freely submits itself to the spirit direction can hope to survive the mortal time-space existence as an immortal child of the eternal spirit world.”
42:12.15 (484.3)
A Thought to Ponder from The Urantia Book
In regard to my understanding as someone who has read the Urantia book, this is how I understood it: This suggests that embracing spiritual guidance is every vital for transcending the limitations of our temporal existence, allowing the mind to endure beyond mortal constraints and connect with the eternal spiritual realm. It also signifies a transformative journey that is towards becoming an immortal child of the eternal spirit world through a willingly submitted mind.
