Spiritual evolution, or the soul's journey through species.

We see that there are many forms of life, but where do they come from?

The dog, the cat, the tree, the reptile, the various insects, the many fish—where do they all come from?

Perhaps there is evolution, but all the various forms of life exist simultaneously: the fish, the human, the tiger, and all other beings. These forms of life are comparable to different types of apartments in a city.

We will inhabit one according to the rent we can pay, but the fact remains that all exist simultaneously.

Similarly, a living being, according to its karma, can occupy one of these bodies: but there is also evolution. After the fish, the next stage will be plant life. From there, the living being can become an insect. From the insect stage, it will move on to that of a reptile, then a bird, then a mammal, and finally evolve into a human form.

If the distinct soul proves worthy of its human condition, it can continue its evolution. Otherwise, it will have to reenter the evolutionary cycle. This human form therefore marks an important stage in the evolution of the living being.

What is the true meaning of the free choice and free will that God grants us?

Only pure, natural, and spontaneous love can satisfy God, an immaculate love, without a trace of any personal desire. This is the main reason why God grants every living being their freedom of choice. This free will allows us to love or not love the Eternal. The choice is left to every living being. Beings who devote their love to the Eternal are found in the spiritual world, while those who do not want to love Him are relegated to the material universe.

Those who do not love God or who are envious of His position as Supreme Beneficiary cannot remain in the spiritual world. When this happens, they are immediately cast out of the spiritual world, for envy of the Lord does not exist there. The choice to love the Eternal or not has existed within each of us from all eternity.

The choice is ours. To love God, to obey and serve Him with love and devotion, and to live with Him in His kingdom, or to choose not to love Him, to gratify our own senses, and to undergo in the material universe life after life, rebirth, death and suffering repeatedly.
