17 Thou that hast fashion'd twice this soul of ours, So that she is by double title thine, Thou only know'st her nature and her powers, Her subtle form thou only canst define. 18 To judge herself, she must herself transcend, As greater circles comprehend the less; But she wants power her own powers to extend, As fetter'd men cannot their strength express. 19 But thou bright morning Star, thou rising Sun, Which in these later times hast brought to light Those mysteries that, since the world begun, Lay hid in darkness and eternal night: 20 Thou, like the sun, dost with an equal ray Into the palace and the cottage shine, And show'st the soul, both to the clerk and lay, By the clear lamp of oracle divine. 21 This lamp, through all the regions of my brain, Where my soul sits, doth spread such beams of grace, As now, methinks, I do distinguish plain Each subtle line of her immortal face. 22 The soul a substance and a spirit is, Which God himself doth in the body make, Which makes the man; for every man from this The nature of a man and name doth take. 23 And though this spirit be to the body knit, As an apt means her powers to exercise, Which are life, motion, sense, and will, and wit, Yet she survives, although the body dies. THE SELF-SUBSISTENCE OF THE SOUL. 1 She is a substance, and a real thing, Which hath itself an actual working might, Which neither from the senses' power doth spring, Nor from the body's humours temper'd right. 2 She is a vine, which doth no propping need, To make her spread herself, or spring upright; She is a star, whose beams do not proceed From any sun, but from a native light. 3 For when she sorts things present with things past, And thereby things to come doth oft foresee; When she doth doubt at first, and choose at last, These acts her own,[1] without her body be. 4 When of the dew, which the eye and ear do take, From flowers abroad, and bring into the brain, She doth within both wax and honey make: This work is hers, this is her proper pain. 5 When she from sundry acts, one skill doth draw; Gathering from divers fights one art of war; From many cases like, one rule of law; These her collections, not the senses' are. 6 When in the effects she doth the causes know; And seeing the stream, thinks where the spring doth rise; And seeing the branch, conceives the root below: These things she views without the body's eyes. 7 When she, without a Pegasus, doth fly Swifter than lightning's fire from east to west; About the centre, and above the sky, She travels then, although the body rest. 8 When all her works she formeth first within, Proportions them, and sees their perfect end; Ere she in act doth any part begin, What instruments doth then the body lend?
