The most common way people could do time-travel would be a form of meditation in which you don't get caught up in your thoughts and don't make patterns of logical consequences follow as a result of your thinking process. It's very hard for most of us to do that if we think about it. But if you start to watch the process by which things come into being, and you begin to witness from the point of view of watching the words form, then you're beginning to move into the non-temporal mindset, or that which is free of time.
