In Source of Life, Léonard Lassalle tells us of the unusual experiences that wove through his life after starting a spiritual training when he was 19 years old.

These experiences came about, not because of an intentional activity of his mind or heart, but rather by trusting and following what came to him spontaneously from his inner nature. Source of Life takes the reader into the intimacy of Léonard's spiritual consciousness and its effects on the every day material needs.

Léonard was born in 1937 in Nice and was raised in the South of France. He attended AS Neill's Summerhill School in England, studied art in Paris and in London where he met Mélinda. They married in 1959 and brought up their seven children in France and in the UK.
