Blood sacrifice.
Aslan
Aslan comes back to life in Narnia through a magical process that involves a deeper magic from before the creation of the world. This magic allows Aslan to sacrifice himself in place of Edmund and then return to life as part of a larger plan to defeat the White Witch and bring peace to Narnia.
Lucy and Susan cannot untie Aslan because the magic involved in the ties is too powerful for them to break. The ties are part of a deeper magic and can only be broken by someone who is willing to sacrifice their own life in exchange for Aslan's.
Aslan must obey the laws of Deep Magic because they were set by the Emperor-Beyond-the-Sea, who is a higher authority than Aslan. The Deep Magic represents the fundamental rules of Narnia and must be followed to maintain balance and order in the world. Going against the Deep Magic would result in dire consequences.
The right by deep magic that Aslan agreed the White Witch possessed was the right to kill Edmund in order to claim him as a traitor, as stated in the laws of the Emperor-beyond-the-Sea.
Aslan has made an arrangement with the White Witch to sacrifice himself in exchange for Edmund's life, as per the Deep Magic from the Dawn of Time. However, there are deeper, older magic forces at play that the Witch is unaware of, and Aslan's sacrifice ultimately leads to her defeat.
The whole story! Aslan represents Jesus, the white witch represents Satan. Perhaps Edmund represents Judas Iscariot. If I had to say one event, it would be when the white witch kills Aslan. At that moment, the white witch is representing Satan, and Aslan is laying on the stone table representing Jesus on the Cross. When Aslan raises back from the dead and defeating the "old magic" (or "deep magic"), it is comparable with Jesus raising from the dead to defeat sin.
Aslan makes a sacrifice for Edmund by offering himself in Edmund's place to the White Witch, fulfilling the deep magic that demands his life for Edmund's treachery. This act of selflessness and love ultimately leads to Aslan's resurrection and the defeat of the White Witch.
The white witch's magic wand was broken during the battle between Aslan's forces and the Witch's army, leading to her defeat and demise.
The deeper magic that the White Witch did not know about was the sacrificial love that Aslan showed by willingly giving himself up to save Edmund. This act broke the power of the White Witch's curse and brought about the resurrection of Aslan, signifying a deeper spiritual truth about love and redemption.
yes,i can call my magic jack.
Lucy and Susan were unable to untie Aslan because the ropes used to bind him were special and magical, requiring someone with a deeper understanding of magic to untie them. The girls did not possess this knowledge or ability, which prevented them from freeing Aslan.
