Here you will find the Poem The Lord Is His Devotees' Slave of poet Sant Surdas
Whatever is a devotee's caste, clan, family, or name, Rama's love for him is the same. Beggar and king are one to him. Say, of what caste could be Brahma or Shiva? Rama will never abide in the egotistic man's heart therefore his slave, Suradasa, has abandoned pride. Rama was born in the Raghu clan Krishna found his home in Gokula. Words fail to tell of the Lord's love universal, all-embracing; Dhruva was a Kshatriya, Prahlada a demon and Vidura the son of a maid: yet the Lord gave them his supreme love, Krishna washed the devotees' feet at the Rajasuya. The Lord is the slave of his devotees age after age. The tongue can't relate his countless deeds. Says Suradasa, the Puranas and Vedas are witness to these.
