Keshava Vedic Astrology refers to the ancient Indian system of astrology, known as Jyotisha, which is based on the position of celestial bodies such as planets, stars, and other astrological elements at the time of an individual's birth. This system uses the sidereal zodiac, which is different from the tropical zodiac used in Western astrology. Vedic astrology involves the study of the twelve houses, nine planets (Navagraha), and 27 constellations (Nakshatras) to offer insights into one's life, purpose, and challenges.
