It’s interesting and encouraging to know that researchers at Harvard, Yale and the Massachusetts Institute of Technology have found the first evidence that meditation increases thickness of the Brain parts which are responsible for processing sensory input and dealing with attention.

"Our data suggest that meditation practice can promote cortical plasticity in adults in areas important for cognitive and emotional processing and well-being," says Sara Lazar, leader of the study and a psychologist at Harvard Medical School. "These findings are consistent with other studies that demonstrated increased thickness of music areas in the brains of musicians, and visual and motor areas in the brains of jugglers. In other words, the structure of an adult brain can change in response to repeated practice."

This is a good news but it doesn’t happen overnight. The increase in size is proportional to the amount of time one has been meditating.
