The whole material world is the creation of the external illusory energy of Godhead and the living entities who forget the eternal relation with Godhead are so to say entrapped by maya to undergo a conditional life under the modes of nature.
Out of eighty four lakhs of varieties or species of life there are only four lakhs varieties of human being.
