Oft and in vain my rebel thoughts have ventur'd <br />To stop the passage of my vanquisht heart, <br />And shut those ways my friendly foe first enter'd, <br />Hoping thereby to free my better part. <br />And whilst I guard these windows of this fort <br />Where my heart's thief to vex me made her choice <br />And thither all my forces do transport, <br />Another passage opens at her voice. <br />Her voice betrays me to her hand and eye, <br />My freedom's tyrants conquering all by art; <br />But, ah, what glory can she get thereby, <br />With three such powers to plague one silly heart? <br />Yet my soul's sovereign, since I must resign, <br />Reign in my thoughts; my love and life are thine.<br /><br />Samuel Daniel<br /><br />http://www.poemhunter.com/poem/sonnet-xxvii-oft-and-in-vain/
