Daoist text Zhuangzi

 Zhuangzi and Huizi were strolling on a bridge over the River Hao, when the former observed, “See how the minnows dart between the rocks! Such is the happiness of fishes.”  
“You not being a fish,” said Huizi, “how can you possibly know what makes fish happy?” 
“And you not being I,” said Zhuangzi, “how can you know that I don’t know what makes fish happy?” 
“If I, not being you, cannot know what you know,” replied Huizi, “does it not follow from that very fact that you, not being a fish, cannot know what makes fish happy?” 
“Let us go back,” said Zhuangzi, “to your original question. You asked me how I knew what makes fish happy. The very fact you asked shows that you knew I knew—as I did know, from my own feelings on this bridge.”

​Zhuangzi was right. Our minds are just a part of nature. We can understand the happiness of fishes—or ants, or inchworms—because what drives us to think and argue about such matters is, ultimately, exactly the same thing.

Mind is consciousness which has put on limitations. You are originally unlimited and perfect. Later you take on limitations and become the mind.

​Ramana Maharshi

Some of the things we can do seem undoable, like heat water with our hands, or chill a candle until it no longer burns. But is it impossible?
Solomon Shereshevsky
lived in Moscow and was a synesthete and memorist. A senesthete may have one or several variations, numbers have colors, words had other colors, or tastes, or smells or shapes. The interesting thing about Shereshevsky is that he could also make himself sweat by recalling running for a train, could make one hand warm by remembering it next to a hot stove, and the other hand cool by recalling holding ice. Further, he could block out pain while in the dentist's chair. I don't know what he thought of while doing it, perhaps he just remembered something else and focused on that.
Kluver-Bury Syndrome arises from a damaged limbic system and leaves people indifferent to pain.
Some blind people with visual cortex injury, have no conscious visual awareness, can still read emotion on people's faces. How? Optic nerves route signals to the visual cortex which is in conscious mind, and to the limbic system which is unconscious. Thus, this subset of blind people (eyes work, but the signals doesn't get to a functioning visual cortex) still respond to smiles, scowls or other facial expressions without realizing why.
The point of these examples is to give us a jumping off point, that is, what else might we be able to do that we assume can't be done because nobody has done it. There's an old story about a South American tribe. When the first tall ships approached from the East, no one in the tribe could see them, no one but the shaman. They tribe had never seen tall ships, never conceptualized anything that big floating on the ocean. Despite the fact right in front of their eyes, they did not see. Only the shaman had cast off his mental limitations, and thus had no false restrictions.
