Throw detailed light on the use of supernatural and mystic elements in "Christabel"

The theme of mysticism is prominent in Christabel. Geraldine is overtaken by a mysterious spell several times during the poem, and near the end of the poem, she somehow transfers the effects of the spell to Christabel. Once Christabel physically recovers from the spell, she still seems transformed. Christabel’s kindness and consideration for Geraldine have disappeared and she begs her father to cast Geraldine out of their home. Christabel goes from selfless to selfish. The ways in which the spells taint Geraldine and Christabel suggest the destructive powers of mysticism.
