Shakespeare's Sonnets: Lord of my love, to whom in vassalage

Lord of my love, to whom in vassalageThy merit hath my duty strongly knit,To thee I send this written ambassageTo witness duty, not to shew my wit.Duty so great, which wit so poor as mineMay make seem bare, in wanting words to shew it,But that I hope some good conceit of thineIn thy soul's thought (all naked) will bestow it:Till whatsoever star that guides my moving,Points on me graciously with fair aspect,And puts apparel on my tottered lovingTo show me worthy of their sweet respect. Then may I dare to boast how I do love thee, Till then, not show my head where thou may'st prove me.
