The Lord and Sri Aurobindo

"what is the difference between the Lord and Sri Aurobindo ??"

The Mother replies : " There is no essential difference, but the Lord is All and Sri Aurobindo is a part but conscious of the Supreme Lord of whom He is an emanation ." The Lord, the Mother adds, does not have "a practice particular form.
He  has all possible forms and He is also beyond all forms.... That is why He sends upon earth His Avatars so that the human beings can more easily  meet Him, see Him and get in contact with Him." And Sri Aurobindo is " a permanent Avatar of the Lord ." Though he has withdrawn from this physical world, he continues to work for it from a subtler habitation."He Has" the Mother announces "a permanent home in the subtle  physical -- ( the region closest to the earth -- physical)  where all those who wish to see Him can go and see Him. There in the subtle physical , His form is similar to the one He had upon earth , but with the splendid peace of immortality ."
