What then is the nature of poetry, its essential law? what is the highest power we can demand from it, what the supreme music that the human mind, reaching up and in and out to its own widest breadths, deepest depths and topmost summits, can extract from this self-expressive instrument? and how out of that does there arise the possibility of its use as the mantra of the Real?
Not that we need spend any energy in a vain effort to define anything so profound, elusive and indefinable as the breath of poetic creation; to take the myriad-stringed harp of Saraswati to pieces for the purpose of scientific analysis is a narrow and barren amusement. But we stand in need of some guiding intuitions, some helpful descriptions which will serve to enlighten our search; to fix in that way, not by definition, but by description, the essential things in poetry is neither an impossible, nor an unprofitable endeavour.
