Shloka 23: तद्विहीनं जाराणामिव॥ २३॥

tad-vihīnaṁ jārāṇāmiva.

तद्-विहीनं - love without the knowledge of the glory of the Lord; जाराणां - of couples indulging in illicit love; इव - like 

If they did not have that knowledge of Krishna’s divinity, then their love would have been illicit love similar to that of a mistress for any of her men.

Shloka 24: नास्त्येव तस्मिन्स्तत्सुखसुखित्वम्॥ २४॥

nāsti eva tasmins tat-sukha-sukhitvam.

तस्मिन् - in that profane love; तत्सुखसुखित्वं - happiness in the happiness given to another; न - not; अस्ति - is; एव - surely

In the profane love for the paramour, the sense of happiness in the happiness given to another, surely does not exist at all.
