As a practitioner of meditation and a student of Buddhism, this article offers a limited perspective. In my humble opinion there are many many different modes of consciousness that do not benefit from the simple 'antidotes' described in this article.

But then again I've read Matthieu Ricard's book and find his writing to be less than compelling, very subjective and generalizing ideas that have easy to find exceptions. Not to take away from the absolute wealth of knowledge in Buddhism.

The classic book on this subject is Zen and the Brain: Toward an Understanding of Meditation and Consciousness by James H. Austin - https://en.wikipedia.org/wiki/Zen_and_the_Brain and https://mitpress.mit.edu/9780262511094/zen-and-the-brain/ and http://www.zenandthebrain.com/

Be warned though; it is a huge, dense and detailed book since the author is both a neuroscientist/neurologist and a zen meditation practitioner himself.
