Buddhism question, What do you think of these videos?

Where did you get the sutra? Email the link to me ystarchaser@yahoo.com if you don't mind. Nothin bout the vid but the sutra talks about the oneness of everything. What you see is not what you see, or you see but (truth is) you don't see. Fire's water, water's a tree, etc. Doing is "not doing." Kinda hard to explain, but that's it. Similar ones are "empty is full, n full is empty," n "life is an illusion." They all talk about the same thing. All is the same for they're all one thing.
