Vivekananda  Said  it :
===============
"the  whole  of  the  solid-looking  Nature  is  all  an  Illusion"
--- -------------------
"All experienes    are  in  the  Soul  ; not  in  Nature ".
(Comp. Works : Vol 3 ;  P  71)
=============================================
Century ++  later    Einstein  told   the  same   thing  in  another language  in explaining  properties  of  Electro -Magnetic field for Perceptual  World.
