Silo is the spiritual leader who appears in this confusing, violent and discouraging time. His message is simple and at the same time very deep. His work has surpassed all national borders and found followers in various cultures on all continents.

Silo's public life began in 1969 with two basic events: a speech: “The healing of suffering”  held in front of a handful of people on May 4th in a small mountain village, called Punta de Vacas, on the border between Argentina and Chile.

In the same place he also wrote ‘The Inner Look’, a book published in 1972. Both the speech and the book are cornerstones of his teaching. In the first, he points to the root of violence ... "Only inner faith and inner meditation can end the violence in you, in others, and in the world around you." In the book ‘The Inner Look’ he reveals the true meaning of life. "Here it tells how the non-meaning of life can be converted into meaning and fulfillment. Here are joy, love of the body, of nature, of humanity, and of the spirit. Here sacrifices, feelings of guilt, and threats from the beyond are rejected. Here the worldly is not opposed to the eternal. Here it tells of the inner revelation at which all arrive who carefully meditate in humble search."

Silo spoke to people, gave lectures and participated in major events with the objective of passing his views and teachings to people, from Mexico to Bombay, from Paris to Moscow, from Manila to Copenhagen, in Sri Lanka and Naples, New York and Quito.
Throughout the world, people are following his proposals: Proposals of hope, of the possibility of change, of the certainty that each person  is able to transform themselves into a human being and leave the prehistory of suffering, nihilism and violence behind him. “But in spite of spite of spite of these unfortunate constraints, something soft as a far off sound, something light as a dawn breeze, something that begins gently is opening its way in the interior of the human being..."

Silo has also inspired a new current of thought called Universalist Humanism. It is a school of thought that is both diverse and convergent at the same time and which opposes discrimination, fanaticism, exploitation and violence.

In 2002, Silos's message organized around a book of the same name, and was composed of three parts. The book already known as "The Inner Look" the experience, consisting eight ceremonies which may lead to spiritual inspiration and positive changes in everyday life, and The Path, consisting of reflections and suggestions for personal, interpersonal, and social life. The followers of this spiritual leader, this “Sage from the Andes”, as he is called, form communities that spread silo message in all corners of the earth.

Silo, accompanied by family members and friends, left this time and space on September 16, 2010 in Mendoza, where he lived.
