Those who are faithful students of the Spiritist Doctrine come to understand the path of Spiritual progression by which each of us travels, with the ultimate destination of spiritual perfection.  They come to understand the responsibilities that we have to support one another in this journey, and they understand the influence (upon self and others) of our individual thoughts, attitudes and behaviors. They also respect their spiritual superiors and seek out their help and guidance.

All of these concepts apply in the practice of mediumship.  Mediums who consider themselves to be students of Spiritism and practitioners of its teachings need to understand not only what is expected of them in their role as intermediaries between the material and spiritual realms, but also what will help them to maintain a personal balance, to grow in their own spiritual acquisitions, and to most effectively execute their tasks in the field of mediumship.

Here you will find a list of necessary virtues, or in other words, attitudes, habits, and characteristics that should be regularly displayed by any medium who wishes to be successful in the use of his mediumistic faculty, to protect himself from the potential for downfall and the dangerous influence of inferior beings, and to draw to his side, spirits of an elevated nature who share in his benevolent objectives and who can help him through their counsel, guidance, protection, and friendship.

Keep in mind that mediums on Earth are still human beings and are, just like all of us, on their own path of progression, still with their particular faults and weaknesses.   The superior Spirits do not expect their Earthly mediums to be perfect. They only ask that we make the best effort possible to develop these virtues and will chose as their instruments those who display them most and show the most willingness to work on continuous improvement.

-------------------------------------------------------------------------------

 Seriousness in purpose and use of the mediumship: The serious mediums understand that their faculty has been given to them as a gift by which they can progress spiritually, through their assistance to those in need (both incarnate and discarnate) and in their cooperation in the dissemination of the instructive and inspiring messages.  Therefore, they only use their faculties for good and useful ends.  They do not exploit their brethren of the Spirit realm with requests for help in material matters or inferior spiritual desires, nor do they exercise their faculty to satisfy the curious and indifferent or for any other futile purpose.

Modesty / Humility: The Spirits teach us that pride is the most influential moral imperfection and continuously warn their students of its signs and consequences. In avoiding the downfalls caused by pride, the good medium remembers that he is only a simple instrument of others employed under Gods will and therefore does not assume any merit for the communications that he receives or for the healing energies that he helps bring to another.  He also recognizes that he is not infallible and when duped by deceitful Spirits, he understand that that happened due to a fault in his character or some error in his conduct.  The humble medium is willing to regularly practice self-criticism in order to recognize his own mistakes and avoid becoming unbalanced (through excessive enthusiasm, apathy toward results, or being at mercy of unenlightened Spirits who may plan for his failure). In addition to practicing self-criticism, the good medium is also open to constructive criticism from trust-worthy friends and mentors, and even seeks out advice and mentoring.

Continuous Vigilance: Like any Spiritist, the Spiritist medium can be recognized by his efforts toward inner reform.  The good medium takes care to be vigilant of his thoughts and actions, recognizing the power they have to determine what kind of invisible beings accompany and influence him, and in the medium's case, communicate through him.  This medium seeks to develop the qualities that attract good spirits, such as kindness, good-will, love of the neighbor, and detachment from earthly things, while working to overcome any tendencies or momentary weakness in characteristics that repel good spirits, such as pride, vanity, selfishness, jealousy, hatred, greed, and attachment to the material. 

Perseverance:  A perseverant medium, understanding that the development and exercise of his faculty requires time and patience, will not become discouraged by the obstacles that arise or the time that it takes him to develop his mediumship in a proper way.  If for some reason a medium's faculty has been suspended, he will look inside himself for the cause and wait patiently for when he is allowed (by the spiritual authority that he respects) to resume his work.

Devotion:  A devoted medium is willing to sacrifice his time, energy, habits, pleasures, etc. in benefit of others who suffer. He also recognizes that as a worker of God, and without discrediting any opportunity to serve and fulfill his responsibilities, his ideal is to serve, aid, and heal.

Discipline:  A disciplined medium will take his responsibilities seriously and can be counted on for his punctuality and preparation for meetings, his vigilance and concentration in cooperation with the maintenance of harmonious vibrations during a session, and in his devotion to prayer and study.

Good Will and Benevolence:  A medium with good will attends a meeting with happiness and satisfaction in the opportunity to work and puts forth full effort during the moments devoted to his development.  Out of benevolence, this medium will serve everyone that he is able to help with the same compassion and good will.

Discretion: A medium who practices with discretion will use his faculty to help those in need without making them feel humiliated or shamed, and by keeping for himself (ie not blabbing about) those person's situations, no matter how dramatic or interesting a story they'd make for conversation elsewhere.

Discernment: Discernment, acquired through study and attention to good Spirits' advice, will help the medium to examine various situations and offer wise advice for a sound solution, and it will help in the critical analysis of Spirit communications that should be a regular practice of all mediums and participants of a mediumistic session. 

Disinterestedness: Disinterestedness refers to a lack of material interest and is the virtue by which a medium gives for free what he receives for free.  The disinterested medium exercises his faculty voluntarily for the sole purpose of helping others and seeks no material reward for his work.  Likewise, he does not seek the praise or appreciation of men and humbly awaits his reward in the kingdom of Heaven.
