Were you with me, or I with you

Were you with me, or I with you, There’s nought, methinks, I might not do; Could venture here, and venture there, And never fear, nor ever care. To things before, and things behind, Could turn my thoughts, and turn my mind, On this and that, day after day, Could dare to throw myself away. Secure, when all was o’er, to find My proper thought, my perfect mind, And unimpaired receive anew My own and better self in you.
