From the crown of the head to the soles of the feet, within and without, out to the covering of skin, there is all of that; and there is another, of deathless form, the Self whose form is consciousness, established by nothing but itself.
Word for word
From the head's crown, ending at the soles of the feet, within and without, ending at the covering of skin: that is all of it. Of deathless form is another, whose form is consciousness, the Self, established by nothing but itself.
