The materialist evolutionary theory is not right. I realize that I might discredit myself as once I was an ardent defender of this theory, but I care little. First, it is a theory, one material evidence seems to back up.
The problem is that there are more things that just those chekable by our senses (be those enhanced senses like microscopes, or telescopes or radar rays). As I leant, animals are the descendants of former species, undeveloped enough for the spirit to dwell in them.
This way, those animals what are warm blooded (mammals) are our closest relatives. Science agrees that we are not descendants of todays’ apes, but we have a common ancestor, from where we evolved, and they devolved into the great apes we know today. That common ancestor was a warm blooded creature what made possible the descendance of a spiritual entity, a soul. What is important to realize that we, humans are spiritual beings on Earth. We are the only ones visible on this realm. By this I mean, that animal’s do have souls, and even they have an identity, an ego, but that ego does not manifest itself in this world, but only through the many animal bodies of the species we witness. If by any wonder an animal could talk, it could only adress itself in third person, as it’s consciousness is not limited to a partciular body as in our case, but to all bodies of that species. Animals are not able to say, I am. Only human beings can do that as they bear the spirit in them, on this realm.
Blood is the bearer of the sentient soul, in fact not the physical blood, but the heat element in it, what in terms of alchemy was called air. In alchemy, when the alchemist meant earth, he did not ment soil, but all minerals. When he said water, he meant all what’s fluid, when he meant air, he meant all that’s gaseous, and when he said fire he meant an even higher subtility state. Heat is the lowest form in what the spirit can manifest itself. The highest part of an animal is the heat principle of it’s blood. When the soul descended, the lowest nature of the soul body met the highest part of the animal body. Of course a scientist will smile when he hears about higher, more subtle froms of existance, forgetting that he is the one who willingly chose to accept only physical, sensorial evidence. This sceintist is similar to a person wh sees the ripples in water, the wawes, and thinks that they are based on the combined rules of hydraulics and physics. He forgets the stone that has been cast in water, and generated the wawes. Life is similar. It is unexplained up to this day, They describe to great extent how it works, but they are clueless, why there is it in the firts place. Thye dare not to go further than the tools they have. Yet, it is possible to go further, and this is done by developing the right tools. But because the tools used in mapping the material world, are material tools, the tools necessary to map the spritual (or higher) worlds are spiritual tools. And there is no such thing here but in our souls. That’s why spiritual science cannot be but “subjective”, or introspective, at least in the beginning. That’s why it is dicarrded by short sighted scientists, because they think, something subjective cannot have general value. Yet it may have, if one preserves the objectivity of materialist science when dealing with his own soul. The tools necessary to search and map the spiritual world are the spiritual eyes or chakras. These are developed, built by the disciple, or spiritual scientist. Only some of them are dormant, other needs to be created from the chaos of soul life. When the existing ones are activated, that grants various abilities but those will not be conscious ones. So the new ones are more important, and they need to be created, and how they are created ? By yama and niyama, what rule the astral (manomaya kosha) body. When the new petals (half of those who are said to be there) are created, cleared, activated, than the old ones will work too.
This is where science meets morality, and this is the base of any spiritual discipline and advancement. Interesting how from the animals we arrived to this, isn’t it ? Sometimes I just cannot stop. But this need sto be understod if we do not want to be totally sunk in matter.
To get back to the beginning, that is why there was a significance of fish, as a cold blooded animal, in early christianity, that’s why there is a rule in the Torah to not eat flesh containing blood, that’s why fasting days allowed fish, but not other meat. The lowest spiritual elements, in form of animal instincts are absorbed by using blood as food, and exactly it is that part what needs to be adressed by yama and niyama. That’s why sadhana and discipline go hand in hand.
