Here's all the proof you need to see how your emotions affect your heart, very interesting experiment I think everyone should try.
goto the google app store and download this free app called Instant Heart Rate
https://play.google.com/store/apps/details?id=si.modula.android.instanth...
Then while using the App, think Loving Thoughts, Gratitude, Etc. and watch the reaction, and then think of something that makes you angry, I thought about the Cabal, but it was really hard to muster Anger anymore, I'm assuming that's a good thing. LOL
Just try it out, very interesting the realtime response, it works by your camera measuring the variation of color in the tip of your finger. Very accurate as well, because I clocked it manually.
Just thought I would share that with everyone!
I send loving light to you all!
