There are two kinds of living entities-nitya-siddha and nitya-baddha. The nitya-siddha never forgets his relationship with the Supreme Personality, whereas the nitya-baddha is always conditioned, even before the creation. He always forgets his relationship with the Supreme Personality of Godhead. Here the Lord informs the two brahmanas that they are His servants birth after birth. The phrase birth after birth refers to the material world because in the spiritual world there is no birth, death, old age or disease. By the order of the Supreme Personality of Godhead, the nitya-siddha remains within this material world like an ordinary man, but the only business of the nitya-siddha is to broadcast the glories of the Lord. This incident appears to be an ordinary story about a marriage transaction involving two ordinary people. However, Krsna accepted the two brahmanas as His eternal servants. Both brahmanas took much trouble in these negotiations, just like mundane people, yet they were acting as eternal servants of the Lord. All nitya-siddhas within this material world may appear to toil like ordinary men, but they never forget their position as servants of the Lord.

Another point: The elderly brahmana belonged to an aristocratic family and was learned and wealthy. The young brahmana belonged to an ordinary family and was uneducated. But these mundane qualifications do not concern a nitya-siddha engaged in the service of the Lord. We have to accept the fact that the nitya-siddhas are completely distinct from the nitya-baddhas, who are ordinary human beings. Srila Narottama dasa Thakura confirms this statement:
