Ruins Symbolizing Spiritualism rather than Material Civilization
It is still a mystery how huge Pyramids were built in ancient Egypt. However, a Japanese female psychic named Aiko Gibo (1932 - 2003) found that they were built by engineers who had psychic power as she travelled to Giza in early 1990s in a TV program and invoked the spirit of Hemuin, the main architect of the greatest Pyramid in Giza about 4600 years ago. (https://www.youtube.com/watch?v=vwo_uH00bh0 in Japanese, but explanatory tiles are not correct in Japanese)
According to Hemuin, there were many excellent engineers with psychic power at the time, so that Hemuin mobilized them to build the pyramid. Gibo also spiritually saw many people with a help from living things such as birds carrying big rocks on carriages. The spirit of Hemulin told her that when rocks were successfully lifted and placed on the ground floor workers were very glad and engineers were assured of success in building the pyramid. Therefore, psychic power must have been the key to building the Great Pyramid of Giza.
Indeed, if ancient Egyptians had invented and used special machines or tools to carry and place big rocks in order in a specific and strict manner, those machines should have been depicted in mural painting at the time. However there were no such evidence. It should mean that they used psychic power that could not be expressed in paintings. Gibo also found that Tutankhamen, a king of Egypt about 3,300 years ago, was poisoned to death with special wine. Although some Japanese doubt her psychic ability, most of the people who saw her in TV shows and read her books or who met her in person for spiritual consultation believed in her spiritual power. She wrote that she could see dead men's spirits or future, since she got the power when she had been an infant.
She met Yuri Geller in her TV show sometimes in 1990s and Yuri Geller admitted her psychic ability while she had no doubt on Geller's psychic ability such as bending spoons. Indeed, some psychics are well known for their spiritual or supernatural ability such as levitation or floating of their bodies in the air. A Japanese swami or yoga practitioner made it public in 1990s that he succeeded several times in levitation with evidence photographs (https://lp6ac4.hatenablog.com/entry/20160901).
Although Yuri Geller does not perform levitation, he might be able to float a spoon if he tried hard. Magic tricks can make spoons bent, but spiritual power can, too. It is unknown how Yuri Geller acquired this ability. But, through decades of such performance, he has proved existence of such power. He simply concentrates his mind on a spoon so that it will be bent without physical force. Daniel Dunglas Home who performed levitation in the late 19th century in England, etc. said that sprits helped him float in the air. So, the key to performing miracles seems to lie in minds or spirits. Indeed, Christ Jesus said: "If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you (Matthew 17)."
Aiko Gibo had no such spiritual power and she could not even move a stone with her mind power, but she could hear spiritual vices and music and felt power pulling her up onto the air when she entered into the Great Pyramid in Giza. Napoleon also had a strange experience when he entered into the Pyramid in the late 18th century; his body was levitated to see his future on the ceiling of a corridor in the Pyramid. Later, when Gibo visited the palace in France where the dead body of Napoleon was laid, she spiritually heard Napoleon's voice: "Did you see your future in the Pyramid, too?" Indeed, when she entered the Great Pyramid in Giza, she was overwhelmed by spiritual atmosphere, so that she could not proceed from the corridor before the so-called chamber of the king.
Anyway, the Great Pyramid in Giza seems to be a work of spirits. Ancient Egyptians seem to have preserved spiritual power with which they must have built pyramids. Indeed, there are no mural paintings or drawings of devices or tools that should have been used in building pyramids even if there had been such devices or tools. So, it is natural to suppose that the Great Pyramid in Giza was built by spiritual power of the architects at the time. It was hundreds years before the appearance of Abraham in the history that the Pyramid had been built. There must have been some Egyptians who had spiritual power that had been possessed by the early mankind. Our ancestors who lived thousands years or more ago must have lived with such spiritual power so as to resolve many fatal problems. Without such spiritual or supernatural power, the mankind could not move out of Africa and to South America through Eurasia on foot.
But, as time went by and with development of material civilization, such psychic, spiritual, or supernatural ability seems to have been lost from most of the mankind. So, today none can move big rocks with his psychic power to build another great pyramid. Men of today would use many big building site equipment, which should be more economic and efficient than using psychic power and thousands of workers.
However, Abrahamic religions generated after Abraham's death based on Abraham's strong faith in God have survived in these 4,000 years like the Great Pyramid in Giza. And, most of believers of these religions such as Christianity seem to be assured of their entering Heaven after they die in this world. Yet, souls of those ancient Egyptians who built the Great Pyramid in Giza must have been trapped or locked in the Pyramid, so that Aiko Gibo and Napoleon must have encountered them in the Great Pyramid.
So, when handling big rocks in building the Great Pyramid, the weight of those rocks must have been lessened or decreased mysteriously if not floating in the air, so that workers must have been able to move them easily. Or otherwise, many workers must have died from fatigue. But, there are no records of such a tragedy. Remains around the Great Pyramid in Giza seem to reflect rather peaceful and easy life of those workers.
In conclusion, we had better regard the Great Pyramid in Giza as a ruin symbolizing ancient spiritualism rather than ancient material civilization. But can people in the future, or the 22nd century or later regard the Papal Basilica of Saint Peter in the Vatican as symbolizing spiritualism of the 21st century and before?
John 8, King James Version
30 As he spake these words, many believed on him.
31 Then said Jesus to those Jews which believed on him, If ye continue in my word, then are ye my disciples indeed;
32 And ye shall know the truth, and the truth shall make you free.
