"why go searching for gods and immortals?..."
See in text (Drinking Alone Beneath the Moon)
Having described the spiritual benefits of wine, the speaker asks this rhetorical question. He is not expecting an answer; he has said wine provides spiritual guidance, and so there is no need to go searching. Such a question is presented as a reaction against organized religion, where Li Po’s speaker suggests that one does not need to worship religious idols or gods, but rather merely drink wine to discover spirituality.
