This ocular technique consumed a terrifying amount of eye power. The more extreme one's faith in the great Brahman, the greater the power one gained—but the eye power it consumed was equally terrifying. Even with a technique that could convert other forms of energy into eye power, activating this ocular technique could leave him unable to meet its demand.
Once his eye power was exhausted, he would go blind and need to convert more energy into eye power to recover.
Then there was the ocular technique in his other eye.
This technique was very simple. It allowed Sasuke to sense the presence of Uchiha Brahman. In fact, it was a technique that grew stronger over time. Once he sensed the great Brahman's presence, all Uchiha Sasuke had to do was pray and praise the great Brahman with reverence and sincerity to receive an endless stream of power, growing ever stronger.
This power wasn't permanent. If his faith in the great Brahman diminished even a little, his power would weaken accordingly. And if he abandoned his faith, all the power he had gained would collapse in an instant. But as long as he maintained his faith in the great Brahman, the power he received was real.
He could even use this connection to ask Uchiha Brahman for greater power—or even the chance for divine incarnation!
His ocular technique also had another ability: he could share his faith with others.
"Praise Brahman!"
Uchiha Sasuke clasped his hands together. He could sense a supreme sun, radiating boundless light, warmth, and chaos, floating serenely in a sea of stars. Its eternal light spilled down, illuminating the entire world. Bathed in such sacred radiance, Uchiha Sasuke felt utterly at peace, enveloped in warmth!
"Gratitude! Praise the Kind Father! May your light illuminate the boundless universe
