Spiritism is a lesson of love and everlasting life, in a continued pursuit of self-improvement, and harmony, with all the creation throughout multiple existences.
It is the collection of principles and laws, as revealed by the Superior Spirits, contained in the works of Allan Kardec, which constitute the Codification of Spiritism: The Spirits' Book, The Mediums' Book, The Gospel According to Spiritism, Heaven and Hell, and Genesis.
It is the promised Consoler which came, at the appointed time, to compliment and remind us of what Jesus taught, "reestablishing all things in their true meaning", so bringing to Humanity the true basis for spiritualization.
It reveals new and more profound concepts with respect to God, the universe, mankind, the spirits and the laws which govern life. Even more, it reveals what we are, from where we have originated, to where we shall go, and the cause of our pains and sufferings. Spiritism touches on all areas of human knowledge, of all activities and the behavior of Human Beings.
