Knowing ignorance is strength.
Ignoring knowledge is sickness.
Only when we are sick of our sickness
shall we cease to be sick.
The sage is not sick but is sick of sickness;
this is the secret of health.
Health is not just a physical condition it is also a state of mind. One could have physical illness but not be sick because they do not allow themselves to be consumed by their condition. When you become sick of sickness and you are aligned with your Source you never can be truly sick.
To become sick of sickness you get to a point where you can never go back to that way of thinking or allowing sickness to overcome you. Sickness can be anxiety, depression, a disease but you always have the choice on how you deal with any of these temporary conditions.
Spiritual health is about aligning your body, mind and inner self. Choose to be happy, choose to be healthy and mentally choose to be strong.
