5SENSES AND MIND
We have more than just five senses
As Michael Ashcroft pointed out, the idea that we humans have five senses — sight, sound, smell, touch, and taste—is a belief that dates back 2,000 years to Aristotle.1
Back then, it was a decent guess, but neuroscience has advanced significantly since the days of ancient Greece. It turns out that we have at least four additional senses—and the most underrated and practical of them is known as interoception.
The word has two parts: “intero–” refers to “internal” and “–ception” to “awareness.” In essence, it means awareness of our internal state, which includes learned associations, memories, emotions, and all the data running through the interconnected pipelines of the 100 billion neurons in your body.2
Intero-ception can be contrasted with “extero-ception,” which involves receiving data through the external senses. Most of us tend to prioritize external sense data—like endlessly refreshing a newsfeed after dinner when internally, our body is sending signals to recover and begin winding down.
In the center of the brain lies a remarkably sophisticated piece of biological machinery called the insula. This spongy core is the headquarters for cortical representation, which refers to how your brain processes all the information about your internal state.
Imagine that this area of your brain is like one of those gorgeous 16th-century maps that had “here be dragons” scribbled over the yet-to-be-explored areas. In much the same way, you might think of these cortical maps in our brainstems as having smudges all over them that can only be restored and brought into higher definition through interoceptive exploration.

The whole idea of spiritual life is to just get rid of all concepts and ideas and words and dogmas. All these things that you've carried around for years. When we free ourselves from these things we become totally light.
[We] unburden ourselves of all this. Never look for new words and new sentences and new meanings. All you're doing is adding on to the garbage. Empty yourself out totally and completely and you'll be free."
