This is the first zodiac of the zodiac, the sign of this zodiac is “Medha” or Bheda, the expansion of this zodiac is up to the first 30 degrees of the zodiac (total 30 degrees). This first point of the zodiac moves back every year at a speed of about 50 seconds. This curvilinear motion of this point has given rise to two types of methods in astrological calculations. Indian astrologers do their calculations by considering this point as fixed. This is called the Nirayana method. And the astrologers of the West adopt ‘Sayana’ method by adding Ayanamsh to it. But we should calculate on the basis of Indian astrology. Because this method in calculation is considered correct according to Bhaskar. Aries signifies the east direction, and its owner is ‘Mars’. Its three Dreshkanas (three equal parts of ten degrees) are ruled by Mars-Mars, Mangal-Sun, and Mangal-Guru respectively. The four phases of Ashwini Nakshatra and the first phase of Kattika come under Aries. Each step is of 3.20′ degree, which is equal to one term of Navamsa. The lords of these phases are, respectively, Ketu-Mars in the first phase of Ashwini, Ketu-Venus in the second phase, Ketu-Mercury in the third phase, Ketu-Moon in the fourth phase, Venus-Sun in the first phase of Bharani, Venus-Mercury in the second phase, Shukra-Venus in the third phase, and Shukra-Mars in the fourth phase of Bharani, Sun-Guru in the first phase of Kattika.
