Hi ironoxideman,
Hope you don't mind me explaining my answer to this question. My
Dharma teacher explained to me that emptiness of inherent existence
can be related in this manner. All of us cling to labels and
projections we place upon ourselves and others. For example, we
label a table a table because it fits the description of a table,
it has a top and it has legs.
However, to a baby or a person who had never seen a table
before, it could be a chair or it could be something to chew on. No
one is wrong here because in our own perception, it is what we
label it to be. This does not need to be restricted to just
inanimate objects but it can also be used to explain how we
perceive people or how we view a particular situation in life. My
teacher tells me that this grasping to projections leads us to
suffer and commit more negative karma with or without us
knowing.
This level of understanding of emptiness is on the lowest level
and the highest would be to perceive all reality as empty of
inherent existence. Emptiness is just an english word, it does mean
nothingness. Perhaps, the Chinese word would better explain this
term. The highest realization or direct perception of emptiness can
only be attained via purification of vast amounts of karma,
accumulation of vast amount of merits and finally, meditation. It
is only through meditation, that the Buddha along with many great
Buddhist masters of the past attained this realization.
In Buddhism, in order to be a Buddha, one must have true
renunciation, followed by realization of Bodhichitta and finally
realization and direct perception of emptiness. With these 3, one
has attained full enlightenment.
