... while i am not the best of Buddhist students, i still think.
in the 'Heart Sutra' by Gautama Buddha i read that it has been said:
i also read in Lama Ole Nydahl's Book that understanding emptiness of suffering is understanding of suffering's transience, understanding of suffering's non-permanence.
No suffering lasts forever, any suffering passes with time.
... while my understanding is not perfect probably, i came to following conclusions:
Form is Emptiness, for there is Empty Form that contains nothing within.
Form is Emptiness even if it contains something within, for the Forms within are transient, non-permanent.
Thus, Form is non-dually Emptiness, no matter if it contains Forms within or not.
Emptiness is Form for we can think about Empty Form. Empty Form is both Emptiness & Form.
Emptiness is Empty, non-permanent, from Emptiness a Form can Emerge as well.
Form is also a Form, Empty Form or not.
Even if Empty Form disappears, being Empty, it will Emerge from Emptiness with time as well.
