The aim of this book is to study certain meditation methods followed not only by religious traditions or metaphysical movements that are still alive nowadays like Advaita Vedanta, Kabbalah (within the Jewish tradition), Christianity or Islam (particularly Sufism), but also practiced by other currents or schools that, even though already gone, significantly influenced the West. This is the case of Neoplatonism or Stoicism, whose influence was felt by ancient and medieval Christianity, or Greco-Egyptian Hermetism, which played an important role in the European cultural Renaissance from the 15th century on. A special consideration has been given to Christian tradition, introducing some of the most representative authors of recollection and their meditation methods.
