Matthieu Ricard: Meditate yourself better - opinion - 03 February 2010 - New Scientist (Despite the name, New Scientist is a mainstream magazine for scientists and laymen alike, not particularly New Age.

Thirty minutes a day over the course of eight weeks results in a considerable strengthening of the immune system and of one's capacity for concentration. It also speeds up the healing of psoriasis and decreases arterial tension in people suffering from hypertension."
