When Bhagavan was living in Skandasramam I was once alone with him, sitting on the steps leading up to the Ashram, when a man came to the gate with his family and stopped and called out to me.
When i went there he asked me to ask the Swami whether they could approach him and receive his darshan. I was surprised and said: "Why do you ask permission?" And he said, "We are untouchables."
I started to go back to Bhagavan, but then it occurred to me that even to ask Bhagavan would be an injustice to him, so i told the man that caste had no meaning with Bhagavan and that they would be welcome. The whole party came and prostrated before Bhagavan, and I well remember how for about ten minutes his gracious look dwelt on that untouchable and his family; and how many rich and notable people have I seen fall at his feet without being vouchsafed such grace.
