In geometry, a compass is a plastic or metallic instrument used for drawing circles or arcs. The compass is the first of the three primary instruments used for creating the orderly universe (the Cosmos) out of nothing.
God has created the universe after geometric and harmonic principles, to seek these principles was therefore to seek and worship God. (Wikimedia)
God is a geometer, and creation is construction via the aid of a compass, a pen and a ruler.
Creation, described by the Holy Bible, is simply geometry. It is the use of compass, pencil and ruler to construct angles, lengths and geometric shapes.
Heaven or Paradise described in Revelation 21 is about measurement and construction of geometric shapes such as circle, square and cube. In other words, paradise or the holy city is primarily a special knowledge of geometry.
The drawing compass is an instrument symbolising heaven because heaven is a compass built by a compass. God's throne is the centre of a compass, and our differences are the different directions of the compass. God's throne is mounted on the centre of diversity, and it is only at God - not any human - that the world is reconciled.
Creation begins from drawing a circle whose centre is zero or nothing. The circumference of the circle is, first the Ein Sof, then the glory (the halo) described as the vehicle of the coming of Christ. The dot or centre or origin of the circle is the Monad. In Hinduism, the circle is called Mandala.
Therefore constructing a circle using the compass is drawing the Mandala. Since the circle is heaven, Mandala in Hinduism is the same heaven preached by the Christians.
Heaven is accessible only through knowledge; one must understand that it is a place of peace and harmony before he can enter.
People experience inner balance whenever they devote themselves to drawing the Mandala because heaven is about inner peace and harmony.
We construct geometric shapes whenever we draw the Mandala, which means that we practice geometry and build the same holy city described in Revelation 21.
The compass is the instrument symbolising the construction of the holy city. That is why the compass is synonymous with building.
Masons (brick layers) are builders. And the compass is the most prominent symbol of the Masonic Square and Compasses of Freemasonry.
