Read the lines from "Song VII" by Rabindranath Tagore. My poet's vanity dies in shame before thy sight. O master poet, I have sat down at thy feet. Only let me make my life simple and straight, like a flute of reed for thee to fill with music. What is the effect of the author addressing the poem to a master poet?

It makes the imagined addressee feel more present to the reader.

Explanation:

In this poem, the author refers to his addressee as a "master poet." This master poet is most likely God. The author tells us that he cannot be "vain" and believe himself to be a good poet when he looks at how talented God is. He feels humbled by God's power and the beauty of his creations. By referring to God as another poet, the author makes Him feel more present to the reader.
