Seven are the great Gods below the Trinity, below the Trimûrti. Every religion, again, acknowledges these Seven. The Christian speaks of the "Seven Spirits that are before the throne of God." The Zoroastrian tells us of the seven Ameshaspendas who rule the world. The Chaldean spoke of the seven great Gods. Five only are working and two are concealed, for the universe is in process of evolution and only five stages of it have been reached. Therefore only with regard to five can we definitely speak as to working. The two concealed are beyond our knowing; they are related to future stages of the evolution of the Kosmos. But the five we will now consider. Their names in connection with their functions you know well enough. They are connected with the tattvas of which we were speaking yesterday--the Lord of A'kâsha, Indra; the Lord of Air, Vâyu; the Lord of Fire, Agni; the Lord of Water, Varuna; the Lord of Earth, sometimes called Kshiti (various names are used for him); each of these great Gods has what we may call one region marked out for his working. The matter of that region is the matter in which he works; but in addition to that, each one is represented in the realms of the others by a sub-division on which his impression is especially made. These are the great kosmic planes that I have spoken of marked off from each other by the tattvas. But if we come down to the physical plane, dealing only with Prithivî Tattva, we shall then find that that is also seven-fold in division and that we have physical solid, physical earth or Prithivî, physical water or Apas, physical fire or Agni, physical air or Vâyu, physical ether or A'kâsha. Each of these great Gods works on each plane through the medium that corresponds to the region which belongs to him in the Kosmos as a whole. How often we see those correspondences as it were printed in physical nature. We have light with its seven sub-divisions as seen in the solar spectrums showing the seven colours, and the scale with its seven notes. Colours and notes alike result from vibrations, and are determined by the number of vibrations occurring in a unit of time. As the universe is built by vibrations, colour and sound are factors of the universe at large, and every region is said to have its own colour; the God of that region has his colour--dependent on his vibratory force--which he imprints on the region over which he rules; so that if a Ṛishi looks at the solar system from a higher plane, he not only hears the seven fundamental notes of music, making "the harmony of the spheres," but he sees a gorgeous display of colours, as the sphere of every great Deva with his own colour interpenetrates the others, yielding an iridescent splendour of interfering radiances, the marvellous "rainbow that is round the throne of God." Such mystic expressions have lost their meaning for the majority, because the sight of those who wrote them is but little
