There are some things that are important to anyone learning about seals, not the least of which is a creative and active mind. There are several common seal types, but the key to success is what you are capable of using the for. There are several techniques that are based off of simple seals, but with effects so varied that seeing the connection between them can be almost impossible.
Take, for example, two of my own techniques: Earth Style: Sinkhole, and Lightning Style: Current. The Sinkhole technique creates a pit under my target, and the Current technique channels lightning around whatever it's placed on. On the surface, there is no connection between one and the other. However, they are both based on the same basic seal: the basic containment seal.
Earth Style: Sinkhole projects a containment seal under the ground and sucks in large amounts of dirt and stone under my targets feet, and Lightning Style: Current stores large amounts of lightning chakra, and releases it either at a steady rate or all at once.
Thus we come to second lesson here: never pass off a seal as useless. The containment seal is one of the most basic designs you will ever see in your study of the art of sealing, and you have just learned of two high C ranked techniques based heavily on its design. I also have several more seals, many significantly more powerful, that are either entirely or partially based on that same seal. Indeed, it's hardly a secret to any serious student that the containment seal features heavily in the design of the Flying Thunder God seals that my father created.
Above all, when studying and creating seals. A simple design can often be turned into a powerful, complex technique if you can figure out how to properly amplify the scope, and turn it to your needs. Inspiration is key, and you must be able to find it wherever possible.
