The ten totalities (Tib. ཟད་པ་བཅུ་, Wyl. zad pa bcu) or the ten limitless ayatanas (Wyl. zad par gyi skye mched bcu) are part of the twenty-one sets of immaculate qualities. These comprise four limitless elements, four limitless colours, limitless space, and limitless consciousness.
This means that through one-pointed concentration upon one or other of the elements, the specific quality of that element can be transferred to other phenomena (so that, for example, water or air can be given the solidity of earth so that it can be walked upon). Whereas Aryas can acquire this power only through training, it is the natural ability of Buddhas and is available at their mere wish.
