Body is an instrument of God
Utilize your authority over this body to foster the welfare of the world. This body is but an instrument, an implement given by God. Let it serve its intended purpose. Until the realisation of the purpose for which the implement is given, it is your duty to watch over it vigilantly and protect it from injury and disablement. During winter, woollen clothes are worn to withstand the rigour of the cold gales, but when the cold subsides, they are discarded. So too when the cold gales of material life don't affect us in the least, the material body will no longer become essential. "Thou-art-That" - this is the highest and holiest spiritual maxim! You are the indestructible Atmic principle (Divine Soul). It is to realise and experience this Atmic principle, you have this body! In the process to realise the Supreme Lord here and now, you must take good care of yourself.
- Prema Vahini, Ch 12.
