When birds fly in the air and fish swim in the deep,they do not do so with any conscious art. (...) if they knew this, and set their minds on doing it,they would inevitably fall down and be drowned
~Shen-tzu
(from William Scott Wilson’s introduction to Chozanshi’s
The Demon’s Sermon on the Martial Arts)

When we are preoccupied with ourselves we cannot trust. We second guess with second thoughts the unspoken agreement between ourselves and circumstances. This creates a gap where the winds of doubt rush in to fill the void, resulting in turbulence.

To close the gap we must forget ourselves.
