What is the meaning of The Song-Maker by Sara Teasdale?

Sara Teasdale's poem "The Song-Maker" illuminates the lack of truth many live their lives by. The opening stanza speaks of the "hundred little songs" about love that the speaker has created. Unfortunately for the speaker, here assumed to be female, she had no right to create them for she "knew no whit thereof."
This speaks to the idea that many people tend to believe that they know about something deeply enough to preach on the subject; yet, the more one tries to unravel the secrets associated with subjects such as love, the more the secrets bury themselves.
In the second stanza, the speaker admits to having lost the power to speak on the subject of love, since she now has the power to figuratively "see." This idea suggests that once one possesses the truth behind love, he or she loses the ability to speak on it. It suggests that one becomes mute and deaf once he or she possesses the knowledge of what love truly is.
In the final stanza, the speaker offers readers a reflective view of being knowledgeable about love. She discusses how she once had the ability to sing many songs of love, but now, her voice has gone silent.
In the end, her maturity and lack of foolishness have allowed her to understand that love is something one cannot universally speak about. The idea that she had written hundreds of love songs explicitly speaks to the idea that love constantly changes, and if it changes that much for a single person, one (now knowledgeable of love) realizes that a single person cannot define love for the world around him or her.
