"Heaen and Earth" , as a universal technique, but you can certainly use any other technique of meditation or prayer. The most important thing is that we  do this together at the same time, and  so  create peace for the whole planet in our hearts!

  We all know the immense power our mind has, when inspired by emotion, and how it's able to actually create our reality.  So when numerous people, all around the globe are engaged in the same meditation, and all direct their minds towards one unified goal at the same moment - then we cannot but win, and accomplish our common goal!

See you in radiant meditation space!
Good luck to all of us!
