The production of souls is the secret of unfathomable depth. [ Victor Hugo ]

Music is a kind of inarticulate unfathomable speech, which leads us to the edge of the infinite, and lets us for moments gaze into that. [ Carlyle ]

Who is there that in logical words can express the affect that music has upon us? A kind of unfathomable speech, which leads us to the edge of the infinite, and lets us for moments gaze into that. [ T. Carlyle ]

The deep mellow voice of the waves of the mighty deep is full of mystery and awe; and the ocean moaning over the dead it holds in its bosom, lulls them to unbroken slumbers in the chambers of its unfathomable depths. [ Haliburton ]

That which we foolishly call vastness is, rightly considered, not more wonderful, not more impressive, than that which we insolently call littleness; and the infinity of God is not mysterious, it is only unfathomable, not concealed, but incomprehensible: it is a clear infinity, the darkness of the pure, unsearchable sea. [ Ruskin ]

Love is the river of life in this world. Think not that ye know it who stand at the little tinkling rill, the first small fountain. Not until you have gone through the rocky gorges, and not lost the stream; not until you have gone through the meadow, and the stream has widened and deepened until fleets could ride on its bosom; not until beyond the meadow you have come to the unfathomable ocean, and poured your treasures into its depths - not until then can you know what love is. [ Henry Ward Beecher ]
