Reality can be divided into how things appear and how things really are. Things exist “deceptively” in that they appear differently from how they really are. It seems that things are “out there,” independently and objectively. But actually they are “empty.” Things do exist, but only as projections coming from us due to how we’ve treated others in the past. Humans see a cylinder as pen while a dog might see it as a chew toy due to different karma. Because things are ultimately empty of self-nature, everything is perfectible.
