Mindfulness, concentration, kindness and insight are all mental formations. Taking care of the mind, takes care of the body. They are one.
Breathing in, let go of your worries. Breathing in I am aware of my whole body. Breathing out, I am aware of my whole body. Breathing in, calms the body. Breathing out, calms the body.
A calm rider, a calm horse. A calm horse and rider will find joy in everything they do.
There is no joy without faith. Trust in the process.
