One Moment Meditation
I was delighted to come across this simple, clean explanation of “One Moment Meditation”. There are strategies other than the one he suggests here, but this is the most basic and universally applicable.
If you like the strategy of just focusing on your breathing, as discussed in this video, (and elsewhere on my site), you might also find The Sponge makes a great “Quick Meditation”.
Anyway, I love his presentation!
