A generous mélange of pantheism, panentheism, mysticism, the human consciousness movement, personal empowerment and other New Age elements, Entering the Castle offers Christians a view of how New Age writers pick and choose parts of many traditions (without affirming any of them specifically), including the Bible (either as verses quoted out of context or as characters held up as paragons of a sterilized spirituality). Myss' understanding of truth, heaven, hell, and the soul are are all textbook versions of New Age thinking, as are most of the other terms she uses or defines. Ostensibly about the soul-journey an individual can make based on the mystical text The Interior Castle by Teresa of Àvila, the application of it would put the practitioner in contact with concepts like divine chaos, Jungian psychology, silence as the language of God, the divinity of the individual, and the 'mystical trinity' of matter, the soul, and enlightened consciousness.
