"Hanging again?"
William couldn't help but recall the time he and Jin had faced the newborn church together when the members had chosen to greet the Holy Embryo by hanging themselves in unison.
If it hadn't been for the presence of the "Dusk thin silver liquid," symbolizing death, the situation would have been extremely perilous, and both of them might have died beneath the church.
Lene explained, "Yes, the key to the Fertility Ceremony lies in 'hanging,' and it must be done using an umbilical cord that matches the individual.
If the black umbilical cord hadn't maintained such an intimate relationship with you, William, I wouldn't have suggested proceeding with the ritual."
By hanging with one's own umbilical cord, one can achieve 'Umbilical Cord Around The Neck,' enabling the individual to revisit the sensation of returning to the womb, re-experiencing the entire process of birth, and thus comprehending the sense of being reborn.
