Spirits are the intelligent Beings of creation. They constitute the World of the Spirits, which pre-exists and survives everything. All Spirits are created simple and ignorant. They gradually evolve intellectually and morally, so passing from an inferior order to more elevated levels, till they finally reach perfection where they will enjoy constant happiness. All Spirits preserve their individuality, before, during and after each incarnation.
Spirits reincarnate as many times as becomes necessary in order to achieve their own perfection.
The different corporeal existences of the Spirit are always progressive and never regressive. The rapidity of their progress, both intellectually and morally, depends upon the degree of effort made towards betterment. The relationship of Spirits with Man is constant and has always existed. The Good Spirits do their best to lead us towards goodness and uphold us during our trials, helping us to support them with courage and resignation. Whereas the Imperfect Spirits try to incite us towards evil.
