Earlier, Shri Krishna spoke about the fate of the unfulfilled meditator who goes to an illustrious family after having attained heaven. In this shloka, Shri Krishna talks about another type of unfilled meditators who is born not into a wealthy family but into a family of learned yogis. He also says that such a birth is exceedingly rare.
 
So far, Shri Krishna has spoken about two types of serious seekers who had a clear understanding of meditation but were unable to attain liberation. The difference between the two types of seekers is the presence or absence of desires. The meditator who still harbours desires is born into a wealthy family.
 
Desires are the biggest obstacles in meditation. Only when desires are extinguished can serious meditation begin. That is why this category of meditators is given the chance to fulfill his desires in a wealthy family.
 
The other rarer category of meditator had managed to extinguish his desires, but could not attain liberation because he ran out of time. Since he is not interested in fulfilling any desire, regardless of whether it is heavenly or earthly, he goes straight into a family of yogis after he dies. These yogis are not just accomplished meditators, they also possess “dheemata” or a keen understanding of the scriptures.
 
Such a family provides a conducive environment for this kind of meditator to continue his progress in meditation. He has enough dispassion in him and therefore does not get affected by the the absence of wealth in this new family. In fact he appreciates it because wealth can become a distraction in the path of meditation.
 
Now, do both these types of newly-born seekers have to start their journey from scratch? This is taken up by Shri Krishna in the next shloka.
