This is not an aggressive outflow, as in karate, but one that is both soft and strong at the same time—Stroft. Like the powerful but ghostly magnetosphere that the Earth's hot inner core produces around our planet to defend against the solar wind and cosmic rays, visualize your sphere of energy slowly billowing outward, forming a kind of force field around your person. 5. Engage from within. After you are in a state of Stroft, having grounded yourself, summoned your mettle, and expanded the orb of your inner energy, then you can engage the Hydra . . . but in a particular way.

I half smiled. He was very handsome. “So yep, all up, I'd say he was an interesting, good-looking, ‘stroft’ rooster. That's impressive.”
