As he searched to find meaning in life during his university days, he came to the conclusion that Truth was to be found not in the world of mathematics, but in Buddhism. He has given over 120 lectures and seminars per year all over Japan for those with no background in Buddhism. In March 2012, the original Japanese version of this text was published by Ichimannendo Publishing Co. Ltd. and 170,000 copies have been sold in Japan to date.
