"When the soul is ready for its next step in the upward way, a great change takes place, known as regeneration. Jesus referred to this when He said to Nicodemus: 'Ye must be born anew.' In one of its phases the new birth is a resurrection" (The Twelve Powers of Man 80).
It is important to understand that regeneration is the ongoing, progressive evolution of Spirit in humankind. In one of its phases, it is experienced as being "born anew." This new birth is the result of a new way of thinking which always leads to resurrection or a lifting up of mind/body and affairs.
