The descent of the Silence is not usually associated with sadness, though it does bring a feeling of calm detachment, unconcern and wide emptiness, but in this emptiness there is a sense of ease, freedom, peace. The absorption as if something were drawing deep from within is evidently the pull of the inmost being, the psychic. There is a psychic sadness often when this inmost soul opens and feels how far the nature and the world are from what they should be, but this is a sweet and quiet sorrow, not distressing. It must be something in the mind and vital which is not yet awake to what has happened within you and gives this colour of dissatisfied and distressed seeking.
