Latu, later Swami Adbhutananda, was the first young disciple to come to Sri Ramakrishna at Dakshineswar. The Master gave him various spiritual instructions and guided him carefully in the development of his character.
When Latu came to the Master, he had the habit of making blunt remarks, which was gradually corrected by Sri Ramakrishna.
One day, when a devotee at Dakshineswar misbehaved, Latu harshly reprimanded him.
Master saw Latu’s rude behavior and he was filled with kindness. After the devotee left, he lovingly corrected Latu: ‘It is not good to speak harshly to those who come here. They are tormented with worldly problems. If they come here, and then are scolded for their shortcomings where will they go? In the presence of holy company never use harsh words to anyone, and never say anything to cause pain to another. … Tomorrow, visit this man and speak to him in such a way that he will forget what you said to him today.’
Latu was humbled by Sri Ramakrishna’s loving words and gracious attitude towards him in correcting his weakness. He did as he was told and the following day visited the devotee. He recounts the incident thus: ‘So the next day I visited him. My pride was humbled. I spoke to him very sweetly.
When I returned, however, the Master asked, “Did you offer him salutations from me?” Amazed at his words, I said that I had not.
Then he said, “Go to him again and offer him my salutations.” So again I went to that man and conveyed the Master’s salutations. At this the devotee burst into tears. I was moved to see him weeping. When I returned this time the Master said, “Now your misdeed is pardoned”.
The humility that Latu saw in the Master gradually brought about his complete transformation; after this he was unable to hurt anyone’s feelings.
