healthy?

Health is a state of complete physical, mental and social well-being, and not merely the absence of disease or infirmity.

 (WHO definition of health)

स्वस्थ
The Sanskrit word for healthy is 'svastha'.   
'Swa' means one's own self
'Stha' means being/abiding/establishment.
It literally means self-positioned, that is, one who is centered in Self, the natural state.

To be svastha is to be established in yourself. Only somebody who is well-established in himself will be able to radiate that joy and enthusiasm that we recognise when we see health.

 

To be healthy means being in balance within our Self, knowing our own mind, knowing the weaknesses of our own body, doing what is right and being happy with our life.

(olan rei)

Every human being 
is the author of his own health or disease. 

(Buddha)
