Meanwhile, Mitsuki was within a Training Ground designed by her parents Prince Asante and Ai Kirisawa.
"Mitsuki, before your lessons commence, there are a few things you should know" Prince said.
"What is it?" Mitsuki asked.
"You've heard of the four basic elements out of which the materials that sustain the cosmos are born haven't you?" Prince asked.
"Yes, they are the oldest elements out of which every other element we know of today were born. They are the elements of Fire, Wind, Water and Earth" Mitsuki said.
"Yes, these are the four material elements that form the basis of the cosmos however there is a fifth element" Prince said.
"A fifth element?" Mitsuki wondered.
"Yes, this element is dualistic in nature and one part of this element predates even Time" Prince said.
"What is this element?" Mitsuki wondered.
"It is the element of Light" Prince said.
"The cosmos is actually formed from five basic elements" Ai said.
"Now we are going to teach you about the order of the elements" Prince said.
Mitsuki listened closely.
"These five elements are collectively called Primordial Elements because they existed at the beginning of the World" Prince said.
"Primordial Elements" Mitsuki wondered.
"The oldest element is Immaterial Light predating even Time. Immaterial Light as Zan explained before expresses its nature through Truth, Knowledge and Wisdom and is the reason for the order of the Universe. This is why the Universe has structure instead of being haphazard in nature. The second oldest element also predates Time and is Water. In ancient myths, the cosmos is described as a vast Ocean. At this point the Universe was formless and was filled only with Water and Immaterial Light. The third element to be born was Material Light. Material Light has its nature expressed mainly through Vision. Since Material and Immaterial Light are both the element of Light expressed in different ways, just assume they are a single element" Prince said.
Mitsuki nodded.
"The fourth Primordial Element to be born was Wind. Wind was responsible for separating everything in the Cosmos and you can say it's the reason the Universe isn't compressed to a single point. The fifth Primordial Element to be born was Earth. Earth could only surface once Wind was born so you could say Wind is the reason we currently have landmasses. The final Primordial Element to be born was Fire. Of the five Primordial Elements (Material and Immaterial Light are one element), Fire is actually the youngest. Fire and Time you could say were born simultaneously. Time was actually the last element to be born. Time was born with the birth of the Stars" Prince explained.
"I see" Mitsuki's eyes were wide open in astonishment.
"Now I want you to utilize your imagination. Can you do that for me Mitsuki?" Prince asked.
Mitsuki nodded.
"I want you to picture the entire universe as a balloon filled with Water. The Water in the balloon forms the Vacuum in the Universe" Prince said.
"I see it" Mitsuki said.
"Good, you may have realized from this that the balloon has a fixed capacity after which it will burst" Prince said.
"That's true" Mitsuki realized.
"Good, now imagine that Solid Objects are being placed into the balloon along with the Water and each Solid Object within the Water in the balloon occupies a fixed space. What do you think happens to the Water?" Prince asked.
"In proportion to the mass of all the Objects in the Water, the Water itself is displaced causing the balloon to expand" Mitsuki realized.
"Prince smiled.
"Good observation. This is what happens at the birth of every Star. The Universe expands in response to the birth of a Star" Prince explained.
Mitsuki opened her eyes in realization.
"I see. I never really considered that possibility" Mitsuki admitted.
"Now I want you to picture the balloon again as more objects are being placed into it. As its elastic limit is being reached what happens to the objects within the balloon?" Prince asked.
"They are forced together in an attempt to constrict space and preserve the integrity of the balloon's form. An inward pressure is thus exerted on the objects within the balloon from the elastic borders of the balloon" Mitsuki realized.
"That's how Gravity works. As more objects are added into the balloon forcing it towards its elastic limit, the balloon becomes tighter in an attempt to preserve the integrity of its form. As it tightens, the objects within it are forced together leaving less space for the Water that makes up the Vacuum. The only reason Gravity appears to be invisible is because it works together with the limits of the Universe and can thus only be perceived once one understands what the limits of the Universe are" Prince explained.
"So you're trying to say whenever I utilize the Torrential Push and Pull Of The Moon's Gravitational Force, I warp the very Fabric of the Universe?" Mitsuki wondered.
"Are you finally beginning to comprehend the Scale of your powers? If utilized the wrong way, you could destroy even Planets and Stars" Ai said seriously.
Mitsuki's eyes widened in shock. Then she calmed down.
"Is that why you sealed away vast reserves of my power?" Mitsuki wondered.
"It's only one of the reasons. This reason was decided upon by your mother since she herself nearly distorted the Earth's Gravitational Field in her infancy. There are reasons I also decided on myself and I will explain all of these to you" Prince said.
Mitsuki nodded.
