The value of compassion

I've called a number of articles to your attention recently about the effects of meditation on the brain. Here's another one from the Wall Street Journal called "Scans of Monks' Brains Show Meditation Alters Structure, Functioning". Here's an excerpt:

"We tried to generate a mental state in which compassion permeates the whole mind with no other thoughts," says Matthieu Ricard, a Buddhist monk at Shechen Monastery in Katmandu, Nepal, who holds a Ph.D. in genetics.

In a striking difference between novices and monks, the latter showed a dramatic increase in high-frequency brain activity called gamma waves during compassion meditation. Thought to be the signature of neuronal activity that knits together far-flung brain circuits, gamma waves underlie higher mental activity such as consciousness. The novice meditators "showed a slight increase in gamma activity, but most monks showed extremely large increases of a sort that has never been reported before in the neuroscience literature," says Prof. Davidson, suggesting that mental training can bring the brain to a greater level of consciousness.

Using the brain scan called functional magnetic resonance imaging, the scientists pinpointed regions that were active during compassion meditation. In almost every case, the enhanced activity was greater in the monks' brains than the novices'. Activity in the left prefrontal cortex (the seat of positive emotions such as happiness) swamped activity in the right prefrontal (site of negative emotions and anxiety), something never before seen from purely mental activity. A sprawling circuit that switches on at the sight of suffering also showed greater activity in the monks. So did regions responsible for planned movement, as if the monks' brains were itching to go to the aid of those in distress.

"It feels like a total readiness to act, to help," recalled Mr. Ricard.

Wouldn't it be wonderful to cultivate that total readiness? The good news is that we can.
