Hoffstadter's I Am a Strange Loop is mostly about the role that self-referential systems arguably play in consciousness. But it also argues that parts of someones consciousness can survive after death in others.
There's a lot of that in Landmark, but from the opposite perspective. That is, there's the insight that we are fundamentally a set of "stored procedures" that we've copied from our parents, family, friends, etc. And especially those that helped us survive traumas. Such as being told that we're wrong. Or being excluded by peers. Or feeling like we're on our own.
So you get that most of the time, you're just running that stuff automatically. But if you can learn to notice that you're doing that, you have an opportunity to choose. That is, you learn to be aware of the machinery.
The bad news, though, is that there's no escaping the machinery. It's an ancient evolutionarily honed thing, and you're running on it. So all you can do is notice.
