Our French Brethren place this letter YŌD in the centre of the Blazing Star. And in the old Lectures, our ancient English Brethren said, "The Blazing Star or Glory in the centre refers us to that grand luminary, the Sun, which enlightens the earth, and by its genial influence dispenses blessings to mankind." They called it also in the same lectures, an emblem of PRUDENCE. The word _Prudentia_ means, in its original and fullest signification, _Foresight_; and, accordingly, the Blazing Star has been regarded as an emblem of Omniscience, or the All-seeing Eye, which to the Egyptian Initiates was the emblem of Osiris, the Creator. With the YŌD in the centre, it has the kabalistic meaning of the Divine Energy, manifested as Light, creating the Universe.
The Jewels of the Lodge are said to be six in number. Three are called "_Movable_," and three "_Immovable_." The SQUARE, the LEVEL, and the PLUMB were anciently and properly called the Movable Jewels, because they pass from one Brother to another. It is a modern innovation to call them immovable, because they must always be present in the Lodge. The immovable jewels are the ROUGH ASHLAR, the PERFECT ASHLAR or CUBICAL STONE, or, in some Rituals, the DOUBLE CUBE, and the TRACING-BOARD, or TRESTLE-BOARD.
Of these jewels our Brethren of the York Rite say: "The _Square_ inculcates Morality; the _Level_, Equality; and the _Plumb_, Rectitude of Conduct." Their explanation of the immovable Jewels may be read in their monitors.
Our Brethren of the York Rite say that "there is represented in every well-governed Lodge, a certain point, within a circle; the point representing an individual Brother; the Circle, the boundary line of his conduct, beyond which he is never to suffer his prejudices or passions to betray him."
This is not to _interpret_ the symbols of Masonry. It is said by some, with a nearer approach to interpretation, that the point within the circle represents God in the centre of the Universe. It is a common Egyptian sign for the Sun and Osiris, and is still used as the astronomical sign of the great luminary. In the Kabalah the point is YŌD, the Creative Energy of God, irradiating with light the circular space which God, the universal Light, left vacant, wherein to create the worlds, by withdrawing His substance of Light back on all sides from one point.
