If it be asked why these momentary revelations come and go all too quickly, the answer may be given in Sri Aurobindo's own words to the writer: "It is because the nature remains untransformed. Only when fully transformed can it be illuminated. Until the whole nature is transformed, it cannot hold the Light but must let it go eventually."
