When a flower blooms, bees come of their own accord. In the later part of the 1870s people began to hear more and more about Sri Ramakrishna, and in the 1880s many newcomers came. Forgetting his body, the Master helped the seekers of God. But one day at Dakshineswar he complained to the Divine Mother, like a child: “How is it that You are bringing such a crowd here? I find no time even to bathe or eat. [Pointing to his own body] This is but a perforated drum, and if You beat it day and night, how long will it last?” Then, on another occasion, he prayed to the Mother, “Please give a little power to Vijay, Girish, Kedar, Ram, and Mahendra (M.), so that they may, to a certain extent, prepare the newcomers before they come to me.” Thus Ram was commissioned to teach by the Master. About this same time Ram also received permission from the Master to give a lecture at the Konnagar Harisabha on “What Is True Religion?”
In May 1885 Ram compiled some of Sri Ramakrishna’s important teachings that he had noted down and brought them out in a Bengali book entitled Tattvasara. A few of the devotees, however, objected to this and they reported it to the Master. Sri Ramakrishna called Ram aside one day and said: “Look here, some devotees informed me that you were publishing a book. What have you written?” Ram replied that he had collected some of his (Sri Ramakrishna’s) teachings and put them together in a book. Ram then read some of it to the Master, who said: “Oh, you have written those teachings? Very good. Listen, if you think that you have written them you will get very little response from others; but if you think that the Lord is working through you then it will be in great demand.” Sri Ramakrishna further cautioned Ram: “Do not publish my biography now. If you do, my body will not last long.” Ram obeyed, but after the Master had passed away he wrote the first biography, Sri Sri Ramakrishna Paramahamsadever Jivanvrittanta. Later he enlarged Tattvasara and published it as Tattva-Prakashika (The Teachings of Sri Ramakrishna). He also began to publish a Bengali magazine, Tattvamanjari, to spread the Master’s teachings.
