Time is the substance I am made of

"Time is one of the many, many illusions that the brain bestows upon us," -

says Dean Buonomano, a neuroscientist at UCLA. How it does that is not yet clear, he says. Researchers long believed the brain was ruled by a single clock that kept all its disparate activities in sync, like a pacemaker that sends out a regular pulse—a sort of cerebral Greenwich mean time. But scientists are learning that there is no central clock. Instead, the brain contains lots of little clocks all running at independent rates yet linked by a network.

At this point the future begins to take shape. If scientists gained a better understanding of how neural timing works, we could employ that timing to better use. In the productivity equation, we could effectively make t smaller by making the same amount of time last longer.

Weird as it seems, it can be done. Not long ago, Eagleman became intrigued by the stories one hears of people who experience time slowing—during a car crash, say. (Eagleman himself entered slo-mo briefly as a child, when he fell off a roof.) He wondered: What's really going on? Does the experience gain added vividness only afterward, as it's being recalled? Or does a person's perception of time truly slow down enough to absorb extra information?
Speed the mind, slow the time—sounds like productivity heaven. But surely there's an easier way to tap into the brain's reserve. So far, "smart" drugs, which go in and out of fashion every few years, are largely worthless. Yet a number of researchers are already exploring the possibilities of a real pharmacological solution. With cocaine, your perception of time is more acute, but that doesn't necessarily mean you're getting more done. You can make decisions faster. But are they the best decisions?"
In November His Holiness the Dalai Lama spoke before the Society for Neuroscience, where he encouraged researchers to study the brains of meditating monks.
The Buddisam deffine the Time like this: "Time is the substance I am made of."
So, we can reflect on past events and learn from them, but we cannot influence them. The past has a fixity that contrasts sharply with the more malleable future, where we make choices and influence events.
Therefore, we experience a directionality to time, expressed by a metaphorical arrow pointing from the past, through the present, and into the indefinite future.
