HI Simon, Just a few thoughts. In my view there is no guarentee of any positive result from any meditation technique, bar none. We bring our entire being to the meditational table and who knows what we need to work on? You might go through all kinds of changes before you see more back to back positive results. You just as easily might see no improvements for years and years. While you might grow impatient with this I think you can use your feelings to recognize motivations to change things in your life. Maybe some of these changes will remove blocks and then the flow in meditation will get easier? People have such a wide assortment of experiences in meditation. Some just sleep and sleep and that's all they do in their meditation and for them at that state of their life that is just fine.
If you feel that it is worth the long haul, then stick with your program and see what comes of it. TM can be a window to evolution but just what sort of changes is hard to predict. I wish you well...... Regards, Fred [snip]
