Linji's Free Flowing Qi.

[Shi Da Dao]

'The effortlessness that Linji so strongly associates with becoming the master of any situation is like effortlessness with which we raise a hand in greeting a friend or with which we lift our feet in strolling home through the soft light of dusk. When all things are united as one single body with freely circulating energy, or qi, there is no need for willpower. Living cut off from other beings as free agents in a particular situation is like inhabiting a body that has been partially paralyzed. The legs are still present, but they will move only if we consciously take them in our hands and forcibly change their position. It is only when there is an interruption or blockage in the free flow of energy in our situation that force is necessary in order to revise its meaning - the direction and quality of its movement from present to future.'
