Happiness depends to some extent upon external conditions, but chiefly upon mental attitudes. In order to be happy one should have good health, a well-balanced mind, a prosperous life, the right work, a thankful heart, and above all, wisdom or knowledge of God.

—Sri Sri Paramahansa Yogananda, “The Law of Success”

A century after the birth of Paramahansa Yogananda, he has come to be recognized as one of the preeminent spiritual figures of our time; and the influence of his life and work continues to grow. Many of the religious and philosophical concepts and methods he introduced decades ago are now finding expression in education, psychology, business, medicine, and other spheres of endeavor – contributing in far-reaching ways to a more integrated, humane, and spiritual vision of human life.

The fact that Paramahansa Yogananda’s teachings are being interpreted and creatively applied in many different fields as well as by exponents of diverse philosophical and metaphysical movements, points not only to the great practical utility of what he taught, but also to the need for some means of ensuring that the spiritual legacy he left not be diluted, fragmented, or distorted with the passing of time. For this purpose Paramahansa Yogananda founded Yogoda Satsanga Society of India also known as YSS of India / Self-Realization Fellowship to disseminate his teachings and to preserve their purity and integrity for future generations. He personally chose and trained those close disciples who head the Yogoda Satsanga Society of India / Self-Realization Fellowship Publications council and gave specific guidelines for the preparation and publishing of his lectures, writings and Yogoda Satsanga Lessons. His guidelines are followed as a sacred trust by the YSS / SRF monastic order so that the universal message of this beloved world teacher may live on its original power and authenticity.
