Sri Aurobindo and the Mother never promised physical transformation of their body or any body in their lifetime. They always said that the physical transformation is the last to happen and will take at least a few hundred, if not a thousand years. By its nature, physical transformation could not be an isolated phenomenon as it is the emergence of a new species. At least a certain critical number of human beings who are ready to pass over to the next species is required.
What they did promise and realised was the emergence of a new principle of evolution, a new consciousness, the supramental, into the earthly play. Once this happened, as it did happen, the rest of it including the physical transformation is an inevitability in due course of time through a process somewhat similar to the emergence of modern man after nine subtypes of humanity between the Ape and present humanity.
Affectionately,
