Meditation

It's not just deep breathing...

Meditation has proven difficult to define as it covers a wide range of dissimilar practices in different traditions. In popular usuage, the word "meditation" and the phrase "meditative practice" are often used imprecisely to designate practices found across many cultures. These can include almost anything that is claimed to train the attention of the mind or to teach calm or compassion. There remains no definition of necessary and sufficent criteria for the meditation that has achieved universal or widespread acceptance within the modern scientific community.
