Materialistically speaking, India may not be a rich country today, but India has a vibrant cultural heritage. The depth of some of India's ancient knowledge (e.g., Ayurveda and Astrology) is just excellent, and it makes one wonder if the history of this great civilization is correctly represented in the pages of modern history. Astrology of India is the most comprehensive and complete system of astrology available today, and it is the only one that comes close to answering the just mentioned "twins puzzle". India's astrology can explain how twins can be different. The principles used in India's astrology are so sensitive to changes in birth time that people born within 1-2 minutes can be significantly different in some aspects and similar in others. This approach distinguishes between what a person truly is, wants to be, thinks he is, and what the world thinks he is. It has enough parameters, tools, techniques, and degrees of freedom to model the highly complicated human life.
ASTROLOGY HAS NO CASTE, CREED, RELIGION, OR CONTINENTAL SEPARATIONS.
IT IS THE MOST PHILANTHROPIC SCIENCE.
Early pioneers of modern Indian astrology called it "Hindu astrology" because ancient Hindu sages first taught this system. However, some people do not like this expression because "Hindu" is not a Sanskrit word. This word was later coined by the Western invaders from the name of a river flowing on the north-western border of India (river "Sindhu" or "Indus"). They used the word "Hindu" to describe the land and the people on the eastern side of this river.
India's ancient religion had no single propagator or prophet. This religion consisted of wisdom that revealed itself to spiritual masters of many generations. So there was no name for this religion, and the word "Hindu", coined by Western invaders, was accepted by the world. However, as already stressed, this word finds no place in Sanskrit literature. Some people do not like using a non-Sanskrit word to describe India's astrology, considering that most of India's classical literature on astrology appeared in Sanskrit.
Later, day authors came up with the name – "Vedic astrology". The word "Vedic" means "about Vedas". Vedas are the sacred scriptures of what is known today as Hinduism and are supposed to contain knowledge of all subjects.
Moreover, astrology, in particular, is supposed to be a "Vedaanga" (which means a limb of Vedas). In particular, it is said to be the eye of the Vedas. So the name "Vedic astrology" is becoming popular these days. Our School also suggests using "Vedic astrology" or "Jyotish" (meaning "science of light"). Jyotishi is a practitioner of Jyotish, i.e. a Vedic astrologer.
Astrology from the Asian side contains scriptures from Greek, Sanskrit, and Arabic.
