[1][5] A shorter but similar reference to a misleading intermediate consciousness, but without the distinguishing qualifier "zone", is also found in some of the later strata of The Synthesis of Yoga which dates to the early 1940s.
[6] Aurobindo asserted that spiritual aspirants may pass through an intermediate zone where experiences of force, inspiration, illumination, light, joy, expansion, power, and freedom from normal limits are possible.
Those who go astray in it may end in a spiritual disaster, or may remain stuck there and adopt some half-truth as the whole truth, or become an instrument of lesser powers of these transitional planes.
[3]Paul Brunton included Sri Aurobindo's term of the "Intermediate Zone" as a name for a psychological and immature mystical level of delusion and subtle ego.
Once there, egoism becomes stimulated by the subtle forces they have evoked, the emotional nature becomes more sensitive and more fluid, the imaginative power becomes more active and is less restrained.
If a person then falls victim to spiritual error regarding this state, the result is swollen vanity, superstitious credulity, emotions run riot, and wild imagination.
