[Vâg. S. XIII, 18] 'Thou art the earth (bhû),' for this is the earth;--'thou art the ground (bhûmi),' for this is the ground;--'Thou art Aditi,'--Aditi is this earth, for this earth gives (dad) everything here;--'the all-containing,' for on this earth everything is contained;--'supporter of all the world,' that is, supporter of the whole world;--'sustain the earth, steady the earth, injure not the earth!' that is, sustain thyself, steady thyself, injure, not thyself!
