Thanks for your answer Rawn, though I tell you that now I have more doubts :-) You say that thinking about the time counts as an "interruption". I saw it just as a thought...sometimes I get sucked by it and sometimes I just observe it. I have countless of these thoughts and sometimes I can observe them and sometimes not. So... when I get clinged to a thought, this counts as an interruption? If so I think I never passed the first 30 seconds without getting attracted by one of these. Should I open my eyes and check the time at that moment? And then, should I continue the exercise until the next interruption? And for how long should I do this? :-) See..many, many doubts!!!! Can you be more specific on what are interruptions? [Non-text portions of this message have been removed]
