Swami Bhagavan Sri Sathya Sai Baba is all that God is. The Sarva Dharma Symbol He gave for Mankind to treasure in the heart and to place the principle It proclaims into practice. Its origin is Divine. Its message is the unity of all man's religions and of all beings. The Sarva Dharma Symbol embodies the essential and complete Divine Message for this and for all ages:

The Sarva Dharma Symbol employs a primal geometry called Divine Proportion, Golden Section, Golden Proportion or Golden Ratio

The Divine Proportion is the universal and invariable standard of perfection and beauty. It is a special relationship between two differently sized parts of one thing: for example, between the long side and the short side of a rectangle. Only one very special relationship may be called the Divine Proportion. And that is when the parts of the one thing are related to one another as 1 is to 1.6, or more precisely, as 1 is to 1.6180339... . The Divine Proportion is represented by the Greek letter phi.

The Divine Proportion is that point at which a line divides such that the long segment is to the short segment as the whole line is to the long segment:

The Divine Proportion is employed by Nature Herself in many ways to organize plants and animals. It is not a man-made ratio or a man-made standard of Beauty. The Divine Proportion is primal, Ur-, the Loveliness and Harmony God is and used to create the Cosmos. He set the Divine Proportion as the root of the world. The world issues from the Divine Proportion. The Divine Proportion is independent of human whim and artifice. It is the Ur-Form or Arche-Type by means of which Life has to become manifest. Without the Divine Proportion, there is no Cosmos, no Life. The Divine Proportion is Divinity. It is the Logos.

We should therefore revere the Sarva Dharma Symbol and imbibe the significance of It and of the Divine Proportion which It enshrines. The Sarva Dharma Symbol is the definition of world peace, unity and prosperity. Politics cannot do it. The Divine Proportion is it. We must be little Divine Proportions, little presences of Sublime Beauty, which is Bliss ... God. We will have a happy and worthwhile life, and all of our desires will be fulfilled, if we do this one thing. Such is the wonder, the beneficence of Swami's gift, the Sarva Dharma Symbol.
