In answer the Lord says: putra-dara-grhadisu, with regard to sons, wives, homes, etc. From the use of 'etc.' (it is understood that this fondness is) even with regard to others who are liked very much-retinue of sevants and so on.

And nityam, constant; sama-cittatvam, eanimity of mind, mental eipoise;-with regard to what?-ista-anista-upapattisu, the attainment of the desirable and the undesirable; mental eipoise with regard to them, always, without exception. One does not become happy on the attainment of the desirable, nor does he become angry on the attainment of the undesirable. And that constant eanimity of mind which is of this kind is Knowledge
