Surrender to the Battle

What does it mean to 'surrender to the battle'?

The Seer:
A snowboarder, surfer or skier knows that they have to apply themselves to their sport in full surrender to the environment. A dancer does not analyze the music, but becomes at one with the drum. A pianist's hands have to move so rapidly across the keyboard, that there is no time for analyses; he or she has to become the music. That's what surrendering to the battle means. It's a state where reason is silenced and instinct takes over.
