Our body's cells must hold the Immortal's flame.

=Impediments to the Transformation=
==Subconscious Plane==
The risings of the subconscious, its effects upon the mind and body, are mostly automatic, uncalled for and involuntary; for we have no knowledge and therefore no control of the subconscient. It is only by an experience abnormal to us, most commonly in illness or some disturbance of balance, that we can become directly aware of something in the dumb world, dumb but very active, of our bodily being and vitality or grow conscious of the secret movements of the mechanical subhuman physical and vital mind which underlies our surface,—a consciousness which is ours but seems not ours because it is not part of our known mentality. This and much more lives concealed in the subconscience.

==Physical Mind==
This body-mind is a very tangible truth; owing to its obscurity and mechanical clinging to past movements and facile oblivion and rejection of the new, we find in it one of the chief obstacles to permeation by the supermind force and the transformation of the functioning of the body. On the other hand, once effectively converted, it will be one of the most precious instruments for the stabilisation of the supramental light and force in material Nature. <ref>http://incarnateword.in/cwsa/28/the-vital-being-and-vital-consciousness#p16</ref>

The physical mind] is closely connected with the brain functioning. All these things—irritation, grief, fear etc. etc.—can become entirely discharged of thought content and felt simply as a physical sensation in the cells, not accepted by the thought (even in the physical mind), not shared in by the emotional being—a wave brought from outside into the material body consciousness.
