Practically-speaking, I would suggest this technique: sit and observe sensations in the body for awhile (as one has done previously), and then change one's attitude towards discursive thoughts; any discursive thoughts that come up are now interesting, and instead of ignoring them or noting them, one should ask an interested question such as: "Why do I feel that way?", "What do I think / how do I feel about that?", "What does that remind me of?", etc. as appropriate. As more discursive thoughts occur, simply keep following them with one investigatory question in mind or other, without censoring them. If you start having a "first-person" relationship towards them, that's fine, but don't let your awareness get too mucked up. Keep body sensations in awareness as much as is practical. After awhile (generally with stronger concentration, or after getting "deeper" into things) it may be possible to drop the interested questions, and merely have an interested attitude. I found it best to assume that the point of engagement with discursive thoughts is to bring subconscious material into consciousness, so according to that assumption, there's no need to build any grand theories, or employ too much grand theorizing about what one "really" thinks, unless enough hidden material has been revealed to make some psychological truth or other about oneself blatantly obvious (and in this case, the grand theorizing may just be epiphenomenal to the therapeutic effect).
