। ॥ १४ ॥
In plain words
Of all these embodiments, the human body is the highest one reaches. Only there does a noble birth, a lineage, become possible. And only there, too, can one weigh the customs of one's own family, or take up the study of scripture.
Close to the Sanskrit
Among these, the human body is the final attainment; there arises noble birth and lineage. There too, the consideration of one's own family customs, and the currency of scripture.
