Explanation:

The Lord says in the Gita that ‘this body’ is the kshetram. The word ‘this’ denotes only a single body. The word ‘this man’ denotes only one specific person. If the Lord meant that the body of every human being is a kshetram, He would not have used the word ‘this’. Then the statement would be ‘the body is said to be kshetram’. Alternatively, the Lord would have used the word ‘every’ before body so that the statement becomes ‘every body is called as kshetram’. Both these options are not used in the verse. Hence, the word ‘this’ denotes the body of the Lord alone.
