Sariputra, form does not differ from emptiness,
As noted earlier, like all phenomena, form is devoid of any inherent self-abiding nature. This devoidness (emptiness) is not a quality which a form gains in the course of its (momentary) existence but is infused with it from the very beginning. Quantum physics, as noted earlier, posits the energy of silent pulsation at the core of everything in the universe, thus defining for us emptiness or sunyata as the "core energy"; in this light it is possible to see all forms emerging out of this silent pulsation as in waves or particles at the cellular level.
The sutra insists that form is emptiness. There is a critical difference between form being empty and form being emptiness. Sunyata, in Prajnaparamita sutras, is the ultimate nature of reality; at the same time it does not exist apart from the phenomena but permeates each phenomenon. Therefore, sunyata cannot be sought apart from the totality of all forms. And, although all forms are qualified at their core by sunyata, its presence does not negate the conventional appearance of form. In this sense, emptiness is dependent upon the form it qualifies, as much as form is dependent on emptiness for its qualification. Thus form is emptiness, and emptiness is form. At its core level, form does not differ from emptiness nor does emptiness differ from form.
