Vol. 1, Page 87 THE SEVEN MYSTIC SENSES.

The Agnishwatha, the Kumara (the seven mystic sages), are solar deities, though the former are Pitris also; and these are the “fashioners of the Inner Man.” (See Book II.) They are: —
“The Sons of Fire” — because they are the first Beings (in the Secret Doctrine they are called “Minds”), evolved from Primordial Fire. “The Lord is a consuming Fire” (Deuteronomy iv. 24); “The Lord (Christos) shall be revealed with his mighty angels in flaming fire” (2 Thessal. i. 7, 8). The Holy Ghost descended on the Apostles like “cloven tongues of fire,” (Acts ii. v. 3); Vishnu will return on Kalki, the White Horse, as the last Avatar amid fire and flames; and Sosiosh will be brought down equally on a White Horse in a “tornado of fire.” “And I saw heaven open and behold a white horse, and he that sat upon him . . . . is called the Word of God,” (Rev. xix. 13) amid flaming Fire. Fire is AEther in its purest form, and hence is not regarded as matter, but it is the unity of AEther — the second manifested deity — in its universality. But there are two “Fires” and a distinction is made between them in the Occult teachings. The first, or the purely Formless and invisible Fire concealed in the Central Spiritual Sun, is spoken of as “triple” (metaphysically); while the Fire of the manifested Kosmos is Septenary, throughout both the Universe and our Solar System. “The fire or knowledge burns up all action on the plane of illusion,” says the commentary. “Therefore, those who have acquired it and are emancipated, are called ‘Fires.’ ” Speaking of the seven senses symbolised as Hotris, priests, the Brahmana says in Anugita: “Thus these seven (senses, smell and taste, and colour, and sound, etc., etc.) are the causes of emancipation;” and the commentator adds: “It is from these seven from which the Self is to be emancipated. ‘I’ (am here devoid of qualities) must mean the Self, not the Brahmana who speaks.” (“Sacred Books of the East,” ed. by Max Muller, Vol. VIII., 278.)
(b) The expression “All is One Number, issued from No Number” relates again to that universal and philosophical tenet just explained in Stanza III. (Comm. 4). That which is absolute is of course No Number; but in its later significance it has an application in Space as in Time. It means that not only every increment of time is part of a larger increment, up to the most indefinitely prolonged duration conceivable by the human intellect, but also that no manifested thing can.
