An examination of the studies and findings behind the science of meditation
A study published in the International Journal of Neuroscience compared 25 meditators of Sahaja Yoga to a group of 25 comparison subjects who did not practice meditation on a range of trait personality measures. The long-term meditators scored significantly lower in personality features of anxiety, neuroticism, psychoticism, and depression and scored higher in emotion recognition and expression.
This suggests that long-term meditation practice leads to higher psycho-emotional stability and better emotional skills.
