Freeman J. Dyson, the renowned Physicist concludes his article entitled: A walk through Ramanujan’s Garden – in Ramnanujan Revisited, Proceedings of the Ramanujan Centenary conference, in 1987, at University of Illinois – with the following advice:

In conclusion, I would like to urge all of you who are working in the many fields of mathematics which have been enriched by Ramanujan’s ideas to go back to the source the collected papers and the notebooks. …. The notebooks … are now appearing in a splendidly annotated version edited by Bruce Berndt. The “Lost” notebook is now accessible to us through the devoted labors of George Andrews. When I started my walk through Ramanujan’s garden 47 years ago, only the collected papers were available. A year after I chose Hardy and Wright's "Theory of Numbers" (Oxford, Clarendon Press, 1938) as a school prize, I won another prize. For the second prize I chose Ramanujan's collected papers. The collected papers have traveled with me from England to America and are still as fresh today as they were in 1940. Whenever I am angry or depressed, I pull down the collected papers from the shelf and take a quiet stroll in Ramanujan's garden. I recommend this therapy to all of you who suffer from headaches or jangled nerves. And Ramanujan's papers are not only a good therapy for headaches, they also are full of beautiful ideas which may help you to do more interesting mathematics.
