We accepted a definition of ourselves which confined the self to the source and to the limitations of conscious attention. This definition is miserably insufficient, for in fact we know how to grow brains and eyes, ears and fingers, hearts and bones, in just the same way that we know how to walk and breathe, talk and think—only we can't put it into words. Words are too slow and too clumsy for describing such things, and conscious attention is too narrow for keeping track of all their details.
