what is "form is emptiness, emptiness is form" ?
This one is from the diamond sutra.
Emptiness as what i understand from my studying is referred to non-attachment to object. Empty does not mean physically non-exist or void. It means to be non-attached to object and happenings around.
non-attached to things does not means bo chap. or dun care.
Non-attachment means any situations that happens, it will not affect you emotionally , mentally in a negative or positive way. but you see that it is part of nature and the work of nature.
If any mishap happens, like an accident, you perform what you need to perform to make the work done well for the victim but you do not get affect by it ( due to wisdom and the understanding of the situation and not attached because you have this non-attachment understanding) and get the job done.
You can compare it between a child and an adult in handling things.
It is like you perform good deed for the benefit of others without any attachment to merits and rewards that comes with performing this good act.
