So my interest is in what other techniques people may have come up with.
What you are already doing is similar to some techniques used in the work. There is also lots of work with other people. There is individual work with teachers that can be similar to psycho therapy or reiki. There is work with other students. Here is one thing you could try with a trusted friend. Diamond calls it open ended inquiry.
Sit facing each other. Set a timer for 15 minutes. One person is totally silent and puts their full attention on the other. The other person talks about their experience of the moment. Some times I experience this is sort of like meditating out loud. After 15 minutes switch roles.
It is hard to teach something like this on line. It normally involves a lecture, a demonstration, doing it, talking about it in a group afterwords, asking questions, doing it again, and so on. You can experiment on your own though.
I wrote this up but if you want to try some of this stuff I would recommend you go to one of the workshops.
