Life includes all things and forms from the highest spiritual down to life in its grossest form; it is the same Life all through, common to all. It is the One Life, the One Spirit in each and all, so that in each being of every grade there lies the potentiality of All-Being. There is that in each which is beginningless and endless, which is changeless; and that, though illimitable, invisible, inconceivable, can be realized by every human being.
