Since we covered a lot of ground in the prior two shlokas, let us do a quick recap. Shri Krishna said that there is only one kind of knowledge that has to be known by a seeker: that there are several bodies or conditionings called fields, and there is just one knower of the field that is as though limited by these bodies due to ignorance or avidyaa. Since there is a lot more to be said about this subject, Shri Krishna lists all the relevant topics that he has to cover.
 
With regards to the kshetra, the field, we have to learn about what it is, what are its characteristics, how does it undergo modifications and what it its source. With regards to the knower of the field, the kshetragnya, we have to also learn what it is, what are its powers and what are its effects. This is the theoretical aspect of this chapter. All this will be covered in just a few shlokas, or “in brief” from Shri Krishna’s standpoint, but we will study it elaborately.
 
Another topic that will be covered in this chapter is the comparison between the individual and the world, how does the individual come in contact with the world, how does he transact with the world, and what are the means of knowledge he can use to maintain the awareness of the field and its knower throughout his life. This is an extremely practical and useful aspect of this chapter.
