The important classic on Muhortha, the electional astrology. The book gives a comprehensive introduction to the calculation of muhoortha for various electional muhurthas. A copy of the ephemeris and the kalaprakasika is the only thing an astrologer would need to give the best muhoorthas for every known function and astrological ritual. The author reveals that the value and practice of the science of Astrology were well understood in India by the ancient Aryans at a period of hoary antiquity. The question of the time at which the science arose is, probably, one in regard to which it is extremely difficult to arrive at a confident conclusion. It is, however, a well-known fact that in the earliest literature of the ancient Hindus, Astrology holds a prominent place.
