João incorporates more than 30 spirit entities. Many of the entities were medical doctors in former times, while others were skilled in spiritual and psychological matters. Although João incorporates only one entity at a time, unincorporated entities may assist with all treatments. You may receive treatment while sitting in the current room, or at any other time and place that is under the influence of the entities, including while enroute to Abadiânia, in one’s hotel room (even prior to visiting the Casa!) and in the assembly hall.

The spirit treatment you receive, the herbs and the blessed water contribute to your healing and continue working over a period of time. The healing process tends to continue to unfold over the 3-4 months (or more) following your visit. Be patient and faithful to your practices of taking the herbs and observing the simple dietary and health rules.

If possible, wait for 21 days after an operation (visible or invisible) before seeing your M.D. or having an x-ray etc.

Much emphasis is placed on the importance of sitting in current. Because the entities work on you in the current rooms, it is every bit as important as going before João in-entity. By sitting in the current room, you both receive and contribute to the flow of spiritual energy

The current rooms are power-places for spiritual practice, raising vibrations and healing. The term "current" (Portuguese corrente) refers to the vital force, or spiritual energy that flows through the room and is sustained by mediums and meditators. You also contribute to the current. During any morning or afternoon session, you may sit in silent prayer or meditation in one of the three rooms. The first current room is entered from the assembly hall. From this room, one enters the second current room, where João in-entity sits while in consultation. This room, in turn, leads to the third current room, which is used for invisible operations and body purification. All current rooms require permission from the Entities to enter.

To get the full benefit of the current rooms, and to not disturb those already there, enter before the sessions begin at 8 a.m. and 2 p.m. Once you enter the current room, plan to stay for the entire session, after all have passed through enroute to the Entity. (The time will vary depending on the size of the crowds.) Keep your legs uncrossed and your hands and arms out of contact with each other, to allow the free flow of energy. Keep your eyes closed and remain silent; the Entities cannot work on you if your eyes are open. If the current is making you too woozy or otherwise uncomfortable, raise your hand and someone will bring you a glass of blessed water to drink. There is also a recovery room for people who really need to lie down for a while. Enter from the assembly room via the second door to the right of the stage or enter through the first current room. A Casa guide will assist you.

A staff member offers spiritual messages in Portuguese throughout the session. At some point João in-entity may pass through the first current room and designate a section to join him in the second room. If you are seated in that section, you may elect to move or remain where you are.

Toward the end of the session, people who will be leaving shortly and haven’t yet passed by the Entity are invited to come say good-bye and receive his blessing. Let your guide know if it is your last session. After current everybody should drink the blessed water provided. The water is sitting in the current room throughout the session absorbing the energy of the session and to complete the session, it is important not to leave the room without drinking the energised water.
