“The process of poetry...is to reveal the potential of what is 'present in the mind' so that writer and reader come to know what it is they know, explore it and realize, real-ize it.” - Denise Levertov
Simply put...write what you know, but more elegantly stated. The fruition of which, of followed, is that we know more, more about the world, our selves, and the relationships. The simple things that make up the real world, and the simple responses that are overlooked by others, are the things we know. Observe, participate, know, stew, write. Re-write and realize.
By doing this, the poet can become an unwitting explorer, which, if others are able to follow the journey, might also learn along with the poet. For sometimes the things we know are deep in the mind, buried, our histories and myths forgotten, disconnected. We can, however, find them and reconnect.
