Well, as mentioned in the article, at the time of writing the Tractatus, Wittgenstein was deeply moved by the kind of spirituality found in Leo Tolstoy's work. However, it's the explicit purpose of the Tractatus to draw a demarcation line between propositions of logic (and by this, meaningful sentences of philosophy) and any mystical or spiritual feelings, thoughts, or faith. So it really doesn't matter at all.
