Note 16-1 — CHAPTER: 16

: From astronomical references in ancient Hindu scriptures, scholars have been able to correctly ascertain the dates of the authors. The scientific knowledge of the rishis was very great; in the Kaushitaki Brahmana we find precise astronomical passages which show that in 3100 B.C. the Hindus were far advanced in astronomy, which had a practical value in determining the auspicious times for astrological ceremonies. In an article in East-West , February, 1934, the following summary is given of the Jyotish or body of Vedic astronomical treatises: “It contains the scientific lore which kept India at the forefront of all ancient nations and made her the mecca of seekers after knowledge. The very ancient Brahmagupta , one of the Jyotish works, is an astronomical treatise dealing with such matters as the heliocentric motion of the planetary bodies in our solar system, the obliquity of the ecliptic, the earth’s spherical form, the reflected light of the moon, the earth’s daily axial revolution, the presence of fixed stars in the Milky Way, the law of gravitation, and other scientific facts which did not dawn in the Western world until the time of Copernicus and Newton.”
