The Vedas give information on various subjects. They have come together and form one book. And in later times, when other subjects were separated from religion - when astronomy and astrology were taken out of religion - these subjects, being connected with the Vedas and being ancient, were considered very holy.
Swami VivekanandaWhat is marriage but the renunciation of unchastity? The savage does not marry. Man marries because he renounces.
Swami VivekanandaEvery Hindu knows that astrologers try to fix the caste of every boy or girl as soon as he or she is born. That is the real caste - the individuality, and Jyotisha (astrology) recognises that. And we can only rise by giving it full sway again. This variety does not mean inequality, nor any special privilege.
