This is in the gospel of srirama christna, where actually the topic was the devotion of the love of the gopes for chrishna. Ramlal, who had a very good singing voice, he sings this song for sirama chrisna and it perfectly illustrates the devotional meaning of vasu de va sarvamiti. There's a beautiful story that sami ramsu das generates about these monks discussing verantabra an jiva jaggat - sentient being with infinite consciousness. The devotee will immediately relate it too to god, to the beloved. They are all related to our christn. So waso deva servam in that sense
