The ancient civilizations - all of them - at some time recommended detachment from the world and meditation. Even today the monks in the monasteries of Europe and the Sadhus of India practice it. A little know fact is that a lot of people of Indian origin practice it too. The world of materialism took over and the practice sort-of died down. Then came the "medical advances" of the last 2-3 centuries and meditation as a health adjuvant was totally discredited. Then sporadically in the 19th century and more firmly in the 20th century came a rapid acceptance of meditation, first for mental peace and lately for all aspects og\f healthy. At the very least this is a healthy trend.
