Some people—nearly all—live in their sensations, to the extent of being conscious only of the present moment. They must be taught the consciousness of their whole life and shown the extent to which their feelings are transient and will be replaced, in the course of their existence, by innumerable contradictory sensations.
(The candle)
Those who have become conscious of their life in its entirety must be taught to identify their consciousness with that of the earth (to enter into a depth of their being which is one with the terrestrial destinies). What is the duration of one life compared with the duration of the earth?
(The gaslight)
Those who have become conscious of the terrestrial life must be taught to identify their consciousness with that of the universe, to find within themselves that which is one with the universe and will last as long as the universe. (What is the duration of the earth in comparison to that of the universe? One breath!)
(The electric light)
Those who have become conscious of the universal life, in all its forms, must be taught to identify their consciousness with That which is Eternal, with That which has never begun and will never end, with the Permanent, the Immutable, beyond Which there is nothing.
And for them will be kindled the undying Light.
(The Supreme Light)
