In plain words
Jagāi and Mādāi belonged to another clan. They too lived by such cruelty. Through their contact with Caitanya they became supreme devotees and went on dedicating their time only to bhajans and dance.
In this way, in every age, through contact with good people, they got rid of the bad feelings, bad ideas and bad qualities in them and developed good feelings, good thoughts and good conduct. So the root cause of these good thoughts is the influence of good company itself. It is not merely a source written down long ago in some history. In any circumstances whatever, good thoughts will one day reach their full form.
In the Tamil country, fifty years ago, there lived a poor family, brahmins. At that time a son was born to the people of this poor family. As the boy grew and grew, the satyāgraha of Gāndhi Mahātmā and his campaign to free this country of Bhārata from its slavery were very strong at that time. Not knowing that he was a barrister, people in the villages heard that he had studied some law, they say, and that having studied as a lawyer he was a great holy soul who had vowed to free the country from its slavery in this way. One day, while the mother was telling some stories with her son beside her: “Son, you too must study law like Gāndhi and make a fitting effort to take away all the troubles of us poor people. You must become a great soul of Dharma. You must become a man of great justice.” So she said. From that day this boy took his mother's words into his heart and went on developing the good thought, ‘One day I must become a lawyer, I must solve the problems of the poor, I must serve them.’ Nursing these good thoughts, this boy went through hardships and somehow joined the B.L. But there were no lamps in his house. Sitting under the street lights, he studied for all his examinations, toiling in many ways. On many days in his life he went hungry, poor fellow.
