PURPORT

Here it is said, ksatram brahma-bhuyam gatam ksitau: although the Dharstas belonged to the ksatriya caste, they were able to convert themselves into brahmanas. This gives clear evidence supporting the following statement by Narada (Bhag. 7.11.35):

yasya yal laksanam proktam
pumso varnabhivyanjakam
yad anyatrapi drsyeta
tat tenaiva vinirdiset

If the qualities of one group are found in the men of another, those men should be recognized by their qualities, by their symptoms, not by the caste of the family in which they were born. Birth is not at all important; it is one's qualities that are stressed in all Vedic literature.
