"Long before time had a name, Ninjago was created by the First Spinjitzu Master using the four weapons of Spinjitzu: The Scythe of Quakes, the Nunchucks of Lightning, the Shurikens of Ice, and the Sword of Fire. Weapons so powerful, no one can handle all their power at once. When he passed away, his two sons swore to protect them. But the oldest was consumed by darkness, and wanted to possess the weapons. A battle between brothers broke out, and the oldest was struck down and banished to the underworld. Peace returned, and the younger brother hid the weapons. But knowing his older brother's relentless ambition for power, he placed a guardian to protect them. And for fear of his own demise, a map for an honest man to hide."
―Sensei Wu to Kai in "Way of the Ninja"
Step 1:
Simple Training
Spinjitzu is a martial arts technique in the world of Ninjago. It involves the user tapping into their innate elemental energies while spinning rapidly, creating a tornado-like vortex of energy around themselves.
Spinjitzu grants the user the ability to transform into a tornado of a specific element and color.
The user is also given the ability to wield the Golden Weapons properly. One of the things required to fully master Spinjitzu is to gain one's True Potential, unlocked once the person overcomes a personal problem that was preventing them from being at peace with themselves.
You must learn to wield the Golden Weapons to truly master Spinjitzu, though not required.
Start with a simple obstacle course. Master it. Do it in your sleep, in your dreams. Time yourself. Get a good time.
Step 2:
Balance. Balance is key. To have perfect balance you must take time each day to quiet your mind and meditate. Not meditating in some false idol or statue but in mind-body connection.
"If you can't change your circumstances, change yourself."
