Reincarnation is one of the most profound and transformative ideas within Spiritism. It provides not only an explanation for life’s injustices but also a clear purpose for human existence. In The Spirits’ Book, Allan Kardec offers a detailed vision of reincarnation that is both logical and hopeful.
In this article, we’ll explore how Spiritism explains the reason we return to Earth, what reincarnation means for our personal growth, and how it fits into the greater plan of spiritual evolution.
What Is Reincarnation in Spiritism?
In Spiritism, reincarnation is the process by which a spirit returns to physical life in a new body after death. This cycle happens not randomly, but for the purpose of learning, repairing, and progressing spiritually.
Kardec defines it as a natural law—not a belief based on faith, but a principle confirmed by the communication of higher spirits and consistent philosophical reasoning.
Key Concepts:
- We are spirits first, bodies second.
- Each life is a lesson, a step in our moral and intellectual evolution.
- We choose or accept our trials before reincarnating, based on what we need to learn.
Why Do We Reincarnate?
According to The Spirits’ Book, reincarnation has several essential purposes:
1. Moral Progress
The Earth is like a school. Each reincarnation gives us a chance to develop virtues like patience, humility, compassion, and forgiveness.
We are not punished for the sake of punishment; rather, we experience challenges that help us grow.
2. Atonement and Repair
When we make mistakes—harm others, misuse our gifts, or act out of pride—we carry that spiritual imbalance with us. Reincarnation gives us the opportunity to make amends, often by facing situations that help us understand the consequences of our past actions.
This isn’t about punishment—it’s about learning through experience.
3. Diverse Experiences
A single lifetime is not enough to develop all aspects of the soul. Through reincarnation, we:
- Experience different roles (rich, poor, healthy, ill)
- Develop empathy by living in various cultures and situations
- Discover our strengths and weaknesses from many angles
This helps create spiritual balance and understanding.
Do We Choose Our Reincarnations?
Surprisingly, yes—to some extent.
According to Kardec, before reincarnating, the spirit meets with enlightened guides and evaluates its progress. It then chooses or accepts the trials and lessons it will face in the next life.
These choices are based on the soul’s need for growth—not on desire or ego.
However, once reincarnated, we do not remember our past lives, because that would interfere with our current lessons. Still, we carry intuitive knowledge, tendencies, and spiritual imprints that shape our personality and life direction.
How Many Times Do We Reincarnate?
There is no fixed number. We reincarnate as many times as necessary for the soul to reach purity and enlightenment.
Some spirits evolve faster through discipline and love; others take longer due to resistance, selfishness, or attachment to material life. But all spirits will eventually reach perfection, because progress is the law of the universe.
Reincarnation and Justice
One of the greatest strengths of the reincarnation principle is how it explains apparent injustices in life:
- Why are some people born into wealth and others into poverty?
- Why do some face illness or disability from birth?
- Why do good people sometimes suffer?
Rather than blaming a cruel or unfair God, Spiritism shows that these circumstances may be:
- Tests for the soul’s strength
- Opportunities for compassion and humility
- Consequences of past lives that need balancing
Thus, reincarnation aligns with the idea of a just and loving universe, where everything has meaning and purpose.
Can We Know Our Past Lives?
Spiritism teaches that while we do not normally remember past lives, there are signs and intuitions that may arise:
- Strong attractions or aversions to people or places
- Innate talents or fears without clear cause
- Dreams or meditative insights that reveal symbolic memories
Some mediums may receive glimpses of their or others’ past lives, but such knowledge must always be treated with humility and caution, avoiding ego and sensationalism.
Reincarnation and the Evolution of Humanity
Spiritism views reincarnation not only as individual evolution, but also as collective human progress. As more advanced spirits return to Earth:
- Societies become more just and compassionate
- Science and ethics evolve
- Violence and ignorance gradually decrease
This process may seem slow, but it is unstoppable. The Earth itself is evolving from a world of trials to a world of regeneration.
Final Thought: Reincarnation as Hope and Responsibility
To believe in reincarnation is to believe in second chances, in justice with love, and in the possibility of becoming a better version of ourselves.
It frees us from fear and guilt, encouraging us to take responsibility for our lives and actions—knowing that every choice matters, and every effort counts.
Through the lens of Spiritism, reincarnation isn’t a burden. It’s a gift from a just and wise Creator, who wants all souls to one day shine with full light.
