Head toward any golden or silver scarab within a stage. As you approach, keep the analog stick pressed slightly forward so that your character continues to slowly advance. Then press the button to bring up the menu to access your ninja skills. If you time it exactly right, you'll hear a sound as the game glitches, almost like an alarm sounding. Look at your karama near the lower left side of the screen and you'll see the number climbing quickly. You are extremely unlikely to activate the glitch on the first attempt, but you can keep leaving and reentering the menu until the desired effect takes place. Then let as many points rack up as you need before you resume play.
