The symbolic interpretation of the tongues of flame rising from the foreheads of the disciples is the light of the Message, the rays of the Christ Spirit in the form of thoughts which were expressed in words. There is a stage in the life of a Seer when the tongue of flame becomes, not only an interpretation of the mystery, but as a reality, as his own experience. The head is the center of knowledge, and, when this organ opens, the light which was covered becomes manifest, not only in idea, but even in form.
