One of the major themes in Disney's Frozen II is the journey into the unknown, which is a common element of the mystical journey into communion with the Divine.
The characters of Frozen II sing about how "some things never change," even amid the changing world. Mysticism unveils those unchanging enduring things, the greater Whole that is also One and Love.
The opening lullaby in Frozen II is replete with mystical symbolism of all kinds, which frames the rest of the film's story.
A famous quote from St. Augustine's Confessions, newly translated.
A late thirdhand account of the First Vision from John Alger in 1893 may be corroborated by some early secondhand (esoteric) references in some songs and hymns recorded in 1833, which may also have connections to a recorded revelation in 1830.
What good is the written or spoken word for uplifting lives and awakening? Is it a means through which we can actively express Love and help bring others to Love?
Is there something beyond traditional moral notions of right and wrong? Is there a higher Law that transcends all other laws? Mysticism has something to say about that.
