Aries 0°-3° 20´ is under the influence of Aries navamsha, 3° 20´-6° 40´ under the influence of Taurus navamsha, 6° 40´-10° under Gemini navamsha, and so on, the last 3° 20’ of this sign Aries being under Sagittarius navamsha. The sign Taurus then commences with Capricorn navamsha, and continues on to Virgo navamsha, when Gemini sign commences with Libra and ends with Gemini navamsha, and is followed by Cancer sign which begins with Cancer navamsha and ends with Pisces navamsha. Leo then commences again with Aries navamsha and follows the same course as the sign Aries. Thus nine successive signs are used to designate the navamshas of each 30 degrees of the zodiac, and so we obtain the 108 navamshas, thus— [Illustration: Figure 17.] But we have already seen that the lunar asterisms, each of 13° 20´, are divided into four padams or quarters each of 3° 20´, and as there are 27 asterisms we have again the 108 amshas or subdivisions of the ecliptic, which undoubtedly were originally associated with the 108 sounds. The fact that these sounds have come to be connected with the signs of the zodiac is due to the affinity which exists between the asterisms and the signs through their respective planetary rulers. For it will be shown that the Ashtottaradasha system of Planetary Periods (which see) recognizes the procession of planetary influence through the 108 padams in the course of 108 years, so that each year comes under the influence of one of these sections of the ecliptic, and the count in each case is made from the position held by the Moon at the time of birth. This subject of Planetary Sounds is of immense interest, but inasmuch as it has been developed solely along Oriental lines and has its basis in a system which did not recognize the Vernal Equinox as a starting-point, but found its yogatara in the first point of As’wini (_Zeta Piscium_), I advise my readers to accept with extreme caution the statement that specific sounds are identified with particular planets or signs of the zodiac, and more particularly would I caution the reader not to rely upon the application of these Initial Sounds to the problems of speculation. I have merely shown in this place how they are derived, and thus have no doubt satisfied the curiosity of those who have seen them in other books where they are given without explanation, authority or warning, and stated as if they had been experimentally proved. CHAPTER XVI PLANETARY HOURS No records that are available to us serve to determine at what period in the course of social evolution the need for a week of seven days first made itself felt, nor can we discover who it was first invented it.
