what are the techniques which helps to make the poem the evening star a nathure poem

William Blake uses certain themes to bring out the natural elements in his poem. One is the theme of pastoral simplicity. It is in the last two lines that the speaker appeals to God for the first time, recognizing his inferiority and potential impotence when it comes to protecting his flock from the fall of grace. The second is political entrapment. Again, the speaker knows that it is during night, when Venus’s “radiant crown” holds the power to put an end to all of daytime’s rules (change the color of the sky, put the flowers to sleep, calm the wind). Alas, the excitement and bliss of the unencumbered will “soon withdraw,” and just as in man’s law-abiding society, the force of opposition governs all of Blake’s inhibitions. Lastly is sexual desire. The speaker here is simply looking for any excuse, any blessing, to act upon his primitive desire to mate with the opposite sex. Knowing an appeal to reason, religion, and God is out of the question; he turns to nighttime’s nature queen in hopes for approval.
