NEPP (2013). "Most Venerable Nichidatsu Fujii". New England Peace Pagoda. สืบค้นเมื่อ 2013-10-31. The Most Venerable Nichidatsu Fujii, founder of Nipponzan Myohoji <...> became a monk at 19 years of age <...> At age 32, after much ascetic practice, he came to realize the basic practice he would follow to bring about peace: beating a hand-drum an chanting Na Mu Myo Ho Ren Ge Kyo. The Most Ven. Fujii believed his mission was to carry out the prophecies of Maha Bodhisattva Nichiren. This included returning the true spirit and teaching of Buddha to India, which had lost those teachings for more than 1,000 years. During his missionary work in India, he developed deep spiritual ties with Mahatma Gandhi, who named him "Guruji", and actually took up the practice of drumming and chanting.
