| | When sensations get fast, consider dropping to monosyllabic blips or dats or something like that or just dropping the noting entirely and staying with rapidly arising and vanishing sensations.
Definitely use the Three Characteristics as a filter once you get fast and consistent enough.
Start by identifying your objects, then break them down into their component sensations and see their true nature whenever possible.
The book you mentioned in your email, Practical Insight Meditation: Basic and Progressive Stages, is the book I mentioned. You can find it in the wiki noted above and many other places. |
