I exposed this question at E-Sangha one year ago, and the recommendation was “let it go”. But after all this time letting go and dont' worrying, I’m still having a heartbeat!! (lucky me
Could there be a hindrance in some way? It doesn’t make me feel annoyed, but sometimes I feel like I am doing something wrong, because everybody talks about “Mindfulness with Breathing” and focusing on one single thing, but nobody says “Mindfulness with Heartbeat”.
There are many instructions about how to fight difference hindrances, they explain with detail how to deal with the most subtle feelings and thoughts, but nobody mentions the heart beat. ¿why? ¿Am I the only one that notice the feeling of the heartbeat when trying to meditate?. It's always present, so what is the meaning of "mindfulness with breathing" for me? I've even tried to focus only on the heartbeat, but I neither can isolate it from the breath.

ps: I'm not having any kind of cardiopathy disorder, it's perfectly normal.
