Spira is a spiritual teacher and writer in the branch of nonduality (Advaita in Sanskrit), exploring the nature of experience in his essays and texts. He has published several books (see below), and a few DVDs with interviews. He holds regular meetings and retreats in the UK, Europe and the US.

He continually works to investigate the nature of mind and reality through his philosophy and pottery. The pottery is the result of the artist's wish to make elegant pieces, in harmony with nature and human awareness
