Even if after reading all about Advaita, you remain confused, then don't despair. Remember the one basic teaching of Advaita and that is - always keep your mind focused on the Guru. That is all you need for now. Attribute everything to your Guru. Yes, your thoughts, your activities, your deeds, your achievements, your chores and every single moment of your day should be attributed to your Guru. That way, "you" do not take credit for absolutely any thing. Nada - nothing at all. Where does that leave "you"? This "you" needs a hook - something that it can take credit for. When left high and dry, the "you" becomes insecure and makes every attempt to regain hold and dominance over every thought and activity.
That is where the Guru comes in. The thought of your Guru can be the Guru with a form and attribute - yes, the human form (Saguna Guru). Nothing wrong with thinking about the Saguna Guru, since He is associated with the Nirguna Guru in your mind. If one feels like thinking about the Nirguna Guru (the Self), then turn your attention to the "I-principle" within. Instead of looking out, look within and immediately all thoughts of the external will vanish and one stands as nothing but the Self. Either way, the Guru should always be on your mind. When one works "mindlessly" or thoroughly absorbed in whatever work one is doing, then one has no thoughts and the Guru is shining.
Let the Guru always shine! Om tat sat!
