We do not know this. But eventually Laghsam Tibetan Meditation in Zurich serves Roche Pharma in Basel to show that their drugs are more effective than practicing meditation. But independent consultant Peter Gamma, Director of the Mediation Research Institute Switzerland:
(MRIS) does not believe in scientific studies which are partly financed by Roche Pharma Basel. For him personally, the books of Matthieu Ricard, PhD., Buddhist monk with PhD. In Cellular Genetics about «Happiness» and «Meditation» are better than the drugs from Roche.
Peter Gamma from www.petergamma.org suggests therefore to read the books of Matthieu Ricard PhDs and to start meditating. You don t need for this the Neurocity Crown from A. J. Keller:
The books of Matthieu Ricard are sufficient to become happy. We know this by our own experience.
