Definition of a (Das) Slave

Once, Sultan went to the ashram of a saint, and stayed there for a few days at the special request of the saint. The saint's name was Hukam Das. Twelve disciples lived with him in the ashram. Everyone had the word ‘Das’ appended to their names. Fakir Das, Anand Das, Karm Das, Dharmdas. Their behaviour was not that of a Das (slave). If their guru asked one of them for some service, he would say that it is Dharmdas's turn; ask him. Dharm Das would say, “It is Anand Das' turn.” Seeing their behaviour, Sultani said that: -

Dasa bhaav nedae nahin, naam dharaaya daas |
Paani ke peeye bin, kaise mit hai pyaas ||

Sultani explained to those disciples, “When I was a king, I had bought a slave.” I asked him, “What do you like to eat?” The slave replied, “The food that the master gives to the slave is his choice.” I asked, “What do you wish? What do you like to do?” He said, “Whatever the master commands, that is my choice.” I asked, “What do you wear?” He replied, “I wear the worn-out clothes given by the master after repairing them.” I freed him. I gave him money too. Remembering his words, I follow the orders of my Guru. I never exercise my volition. I eat what God gives, considering it His command. I serve considering myself a slave. It is mandatory to please Gurudev to please God.” After that, all those disciples started following the orders of their Guru ji with the sentiment of them being slaves, and they started behaving well among themselves. They made their life successful.
