Umberto Vita Vita من عند Sathri, Uttar Pradesh, الهند
كتاب مرجعي جيد!
An interesting explanation of brain chemistry as it relates to meditation, prayer, etc. The author goes a little too far in his simplifications, not only writing for an audience who doesn't know much neurobiology (good idea), but also for an audience who doesn't know much of anything (bad idea).
