While dwelling upon the symbolical mysticism which cannot be ignored in Whitman's whole habit of thought, I may add a further word upon its character.[219] Mysticism appears under several forms. The Indian guru, winning the eternal consciousness by long practices in the gymnasium of the mind; the lover discovering it through the fiery gateways, and tear-washed windows of passion; the poet seeking it in the eyes of the Beauty that was before the beginning of the world; the Quaker awaiting its coming in silence and simplicity; the Catholic preparing for it by prayer and fasting, by ritual and ceremony; the lover of nature discovering it among her solitudes; the lover of man entering into it only by faith, in the strenuous service of his kind: all these bear witness to the many ways of experience along which the deep waters flow. Belonging to no school, Whitman had relations with several of the mystical groups; he had least, I suppose, with that which seeks the occult by traditional crystal-gazing and the media of hypnotic trances or the dreams produced by anæsthetic drugs. He was a mystic because wonders beset him all about on the open road of his soul. In him mysticism was never associated with pathological symptoms; it was, as he himself suggests, the flower and proof of his sanity, soundness and health. He had not learnt his lore from books. Plato and Plotinus, Buddha and Boehme, were alike but half-familiar to him; he never studied them closely as a disciple should. His thought may have been quickened by old Elias Hicks, and strengthened occasionally by contact with the Friends. It often recalls the more leonine, less catholic spirit of George Fox; and the vision of the Soul, standing like an unseen companion by the side of every man, woman, and child, ready to appear at the first clear call of deep to human deep, was ever present to them both, and in itself explains much that must otherwise remain incomprehensible in their attitude. But the world of Whitman was that of the nineteenth century, not of the seventeenth: Carlyle, Goethe and Lincoln, had taken the places of Calvin, Milton and Cromwell. In many aspects the mysticism of _Leaves of Grass_ is nearer to that of _The Republic_ and _The Symposium_, than to that of Fox's _Epistles_ and _Journal_; nearer, that is, to the Greek synthesis, than to the evangelical ardour of the Puritan. Temperance he loved, but he hated the narrowness of negations. * * * * * To return to the book: the thought of the sanity of the Earth is brought to bear upon the problem of evil in a poem[220] which describes how, in spite of the mass of corruption returned to it by disease and death, the earth neutralises all by the chemistry of its laws and life. With calm and patient acceptance of evil, nature refuses nothing, but ever provides man anew with innocent and divine materials. And such, it would seem, is the inherent character of the Universe, and therefore of the Soul.
