This requires gradual training until we reach a state where joy, anger, sorrow, and pleasure no longer stir us internally.
To achieve what the ancients called "wooden stillness, unmoved at the core", we must practice diligently—training until our qi mechanism remains unperturbed by external influences, free from emotional turbulence in any circumstance, and perpetually balanced in neutral harmony .
If emotions have already arisen—such as grief or rage—we must expel them swiftly to restore the qi mechanism's stable equilibrium.
