What is the author's style in Letters to a Young Poet by Rainer Maria Rilke?

Rilke's style is subjective, but he also writes with an objective, detached, contemplative style. The book is a kind of emotional philosophy, a non-judgmental rule book, in which he essentially tells the reader "This is what I've lived, this is what I've understood, and I urge you to think about what I've said" without actually saying "You must live as I have done!" His style is welcoming, not dictatorial, and warm without being intrusive or cloying.
