The body is the vehicle which you have to use for attaining the state of bliss and so, it has to be kept safe and strong for that high purpose. It is an instrument for spiritual effort, which has been earned by the merit of previous births. Every moment, it is proceeding towards dissolution and so time should not be wasted in vain pursuits. It is even better to think of the body as mean and low, rather than raise it to the level of the be-all and end-all of life. Treat it as a wound, which has to be covered by bandage (clothes), treated with drugs (food) and washed (drink); you can get rid of this inordinate attachment, only by that method.
You can get real urge and inspiration to serve others only when you get rid of the identification with the body. When a man suffers from acute stomach pain, his eyes water. Why? Because, the various organs---eye, stomach, etc.---are all of the same body. So too, when one man suffers, your eyes must shed tears and you must be urged to alleviate it. This will happen if you know that you and he are limbs of the self-same Divine Body. The idea of difference (bheda bhava), arises on account of the ignorance of the Truth. When people get angry, they gnash their teeth, but, they take care not to bite the tongue, for the tongue is theirs; if by chance, the tongue is bit, they do not knock the teeth out, for the teeth is theirs. So too, the sick man, the poor man, the suffering man, the illiterate man, the wicked man, are all limbs of the same body, of which we too are parts. The same current activates all. To realise this and to merge in that Unity is the purpose of this life in the human body. (SSS Vol.5)
