old dried leaf:
In your personal experience, what increased the continuity of your awarness?
1. Letting the mind rest wherever it is at the moment. That means not trying to be more mindful/concentrated than I actually am right now. And from there watch the object of awareness (e.g. the breath). This almost automatically leads me to getting more calm and focused.
2. This is linked to 1.: letting go of any tension in body and mind. Like you let go of tension in a muscle.
3. Being more systematic at getting back to awareness whenever distractions arise, i.e. having some kind of small ritual whenever I notice being distracted. For example, when I notice distraction throughout the day I simply greet myself in the present moment ("Hello, there you are! Wanna be mindful for a moment?") and let go of tensions (see 2.) This reduces my tendency to become upset about being distracted. Some people suggest to simply smile whenever you get back to awareness. Something nice like that helps.
4. Instead of fighting distractions simply try to catch as many of those distractive mind moments as possible. But still within the momentary capacity of the mind. If you feel dull, just be aware within that dullness. If you are excited, just be aware within that excitement.
Another thing that has helped where the advices of Ajahn Brahm like the little mantra "This is good enough for me" or putting 100% of the energy into the observer and 0% into the doer.
All these things for me also lead to a higher frequency of awareness re-emerging.
