DMT is a substance that is already in our bodies. DMT is also produced by the body when you were born, when you dream and when you die. DMT is produced by your spiritual organ, called the pineal gland. Normally the enzymes in your body are breaking off the DMT. The function of the MAO-inhabitor is to give the enzymes a temporary break so the DMT can do the work. This leads to a deep inner journey which will show you the Truth.
A MAO-inhabitor is seen as a natural anti-depression. So another function of the MAO-inhabitor is to influence your state of mind. The MAO-inhabitor helps you to relax your body and mind so you are able to surrender to your inner journey and to the guidance of the plants.
In many settings in Europe people are using the Arabic Plant called Harmala. You drink the brew of this plant separate from the Ayahuasca as a preparation to your inner journey. After 15 minutes you drink the Ayahuasca and because of the Harmala you’ll be in a more relaxed state.
