Crystal gazing may be used by practitioners -- sometimes called "readers" or "seers" -- for a variety of purposes, including to predict distant or future events, to give character analyses, for fortune telling, or to help a client make choices about current situations and problems.
In Spring of youth it was my lot
To haunt of the wide world a spot
The which I could not love the less -
So lovely was the loneliness
Of a wild lake, with black rock bound,
And the tall pines that towered around.
But when the night had thrown her pall
Upon that spot, as upon all,
And the mystic wind went by
Murmuring in melody -
Then - ah, then, I would awake
To the terror of the lone lake.
