How are "all types of beings originally formless"?

How are "all types of beings originally formless"? - p100 The Sutra of Hui-neng, Grand Master of Zen: With Hui-neng's Commentary on the Diamond Sutra I'm asking because this page [quoting His Highness the Dalai Lama] says > Immediately thereupon, the intermediate state begins—except for those > reborn in the formless realms of infinite space, infinite > consciousness, "nothingness" or peak of cyclic existence, for whom the > new life begins immediately upon death If we all are originally formless, then our original nature has no intermediate state, while our unenlightened state does. How can that be?
