Each of us spent months/years acclimating to 3D existance...learning first how to use our eyes (if so granted) to percieve depth, then learning we have a voice (again, if granted). Our initiation into 3D took a long time...we've all been 'programmed' by words since we first began to hear...overcoming this programing takes time too.
Our "higher learning" now consists of asking the questions we ask here.
