I was given the opportunity to spend some time with Nichiren Daishonen Buddhists in West Sussex. They were very helpful in giving me some insight into their chanting practice.
POSTSCRIPT: those who assisted me in the making of this video wanted to stress that they do not speak on the behalf of SGI. They also felt that the chanting didn't properly represent how outwardly focused their practice is. They were keen to express that Nichiren Daishonen Buddhism is not primarily about inward chanting - it is about releasing this potential in the lives of others around the wider community/society.
