"Of my own spirit let me be in sole though feeble mastery"

This quote by Sara Teasdale speaks to the importance of self-mastery and autonomy. It suggests that we need to strive to be in control of our own lives and decisions, instead of permitting external forces to determine our actions. Teasdale acknowledges that this is an uphill struggle, as we might be weak and vulnerable to outside influences. Nevertheless, she motivates us to take ownership of our own spirit and to be the masters of our own fate. This quote is a suggestion that we must strive to be independent and to make choices that are real to our own values and beliefs. It is a call to take control of our lives and to be the authors of our own stories.
