Then what does it say to you?
"this spirit will also naturally cease to exist" says to me that the animal spirit will not continue to exist after the body dies. I am not sorry to say that I do not believe that, and I know a lot of Baha'is who do not believe it either.
"After this is the animal spirit, which also results from the combination of elements that are brought together in a single composition. But this composition is more complete, and when by the decree of the almighty Lord it reaches a fuller degree of combination, the animal spirit, which consists in the power of the senses, comes to exist. This power perceives sensible realities—that which can be seen, heard, tasted, smelled, or touched. After the separation and dissolution of these composed elements, this spirit will also naturally cease to exist. It is like this lamp before you: When oil, wick, and flame are brought together, light is produced; but when the oil is exhausted, the wick consumed, and the constituent parts separated, the light will also be extinguished and lost."
Then we have these Bible verses:
Ecclesiastes 3:18-20
18 I also said in my heart about the sons of men that the true God will test them and show them that they are like animals, * for humans and an outcome for animals; they all have the same outcome.m As the one dies, so the other dies; and they all have but one spirit.n So man has no superiority over animals, for everything is futile. o They all come from the dust,p and they all are returning to the dust.q 21 Who really knows whether the spirit of humans ascends upward, and whether the spirit of animals descends down to the earth?
As I interpret this to be saying that animals have a spirit just like humans have a spirit and when the body dies both the animal body and the human body return to dust. Nobody really knows if the human spirit ascends upwards or whether the spirit of animals descends down to the earth.
This is a great glimpse at our Oneness is it not?
In that oneness, in this world there is an apex we can reach, which Abdul'baha describes like this; "All created things have their degree or stage of maturity. The period of maturity in the life of a tree is the time of its fruit-bearing... The animal attains a stage of full growth and completeness, and in the human kingdom man reaches his maturity when the light of his intelligence attains its greatest power and development..."
Consider we are of the same spirit of the animal, to which the spirit manifests in this world as various realities. This spirit has level of realization and as a human we see the mineral, vegetable, the animal, the human and we can with the spirit of faith see the manifestation of God. Our vision takes in all realities and can see what is not seen in this world.
When we all turn to dust, the spirit is not longer in this reality and we then see what the spirit is in the next reality, who know what form the trees take? What form does the animal take? what form does the human take?
What I do consider though, is if we develop our mind, we will see what shape and form all spirit takes. To that end Abdul'baha offered this; "Man must now become imbued with new virtues and powers, new moral standards, new capacities. New bounties, perfect bestowals, are awaiting and already descending upon him."
But show me anything that Baha'u'llah wrote that says what Abdu'l-Baha said on the passage above and I will believe it.
What Abdul'Baha wrote, is what Baha'u'llah offered. Thus it is up to us to consider what it all means.
