Prologue - Explanation of Seals!
Seals are a fundamental part of the Ninja World. However, it is rare to find someone proficient at seals. This book is a guide to mastery of seals. It will explain the mechanics of seals, functions of seals, and general knowledge that will be useful later on. Please note that this is a book that explains the seals and will help you if you go through each and every explanation. Many seals coincide with each other, as I explain in the next paragraph.
Every complex seal there is has been made out of a combination of basic seals. The problem is how to combine the seals in a compact and efficient pattern. If the seal matrix is too large, the seal will loop the chakra through it and the time for it to work will be too long to make the seal efficient. There is also the case of having the seals put together in a way that will cause a completely different outcome. Many seals are created for a specific purpose, and if they don't fulfill that purpose the best they can, it isn't a good seal. This is one of the reasons why seals are so rarely practiced. Also, many complex seals are made up of other complex seals, which can also be made up of more complex seals, so this is another reason why the art of sealing is so rarely practiced.
The Basics are the most important seals. Learn how to make them, what they do, and how to integrate them together, and you will be ready for more complex seals. Seal matrices are very important parts of sealing, as they are made from the Basics to do one job each, and if combined can do those jobs together to do an even harder job. This is the essential element of a complex seal.
Don't worry, because it gets even harder. Next on the list is a Multi-tiered seal, which is tethered together. A few uses for this would be teleportation, substitutions, and making seals with multiple functions. Multi-tiered seals can do multiple functions because of the fact that they are multiple seals. Whereas an advanced seal matrix can do an extremely complex function, such as making a huge explosion with air and chakra, multi-tiered seals can do so much more, such as making an entire storm out of a sunny day, which is changing the weather, and for many decades thought to be impossible, as changing the weather would require the changing of temperature, precipitation, wind speed, and so much more. Doing multiple functions is impossible if you can't tie two seals together, and so the Tethering seal was made, and in that moment, so much more was made possible.
Going even deeper, the Multi-Tiered Chain seals are used for contradictory aspects, such as cooling down fire. One multi-tiered seal would create the fire and the ideal conditions to keep the fire stoked, with an extra seal in there to keep it stoked automatically, while the other multi-tiered seal would take the heat from the fire and disperse it in another location, making the fire cold yet still alive. The chain is necessary for this because one multi-tiered seal is focusing on all conditions for the fire, and if it were connected directly to the fire to take the heat away, the fire wouldn't be strong enough to continue burning. However, since one multi-tiered seal is focusing its entirety on keeping the flame going, while another seal is taking away the heat, the fire will stay strong without the heat it would normally need to survive.
