The Songs of Kabir, tr. by Rabindranath Tagore, intro. by Evelyn Underhill, , at sacred-texts.com
I. 16. Santan jât na pûcho nirguniyân
It is needless to ask of a saint the caste to which he belongs; p. 46
For the priest, the warrior. the tradesman, and all the thirty-six castes, alike are seeking for God.
It is but folly to ask what the caste of a saint may be;
The barber has sought God, the washerwoman, and the carpenter--
Even Raidas was a seeker after God.
The Rishi Swapacha was a tanner by caste.
Hindus and Moslems alike have achieved that End, where remains no mark of distinction.
