One caste, one religion, one God for man; one form and the same blood in all; I cannot find any differences.
There is no reason for caste differences among human beings. All those who possess humanity are human beings. Just as there are different languages and different systems, though human beings seem to be different, there can be no reason for caste differences. Humanity is common to all.
Men may differ in their faiths, their languages and their modes of dressing; but there can be no evil in inter-dining and inter-marriage, because all belong to the same kind of creation.
Sri Narayana Guru
