Maharishi Parasara said — O Brahmin! I have described to you the Jyotisha Shastra as narrated by Lord Brahma to the Sage Narada and by Narada to Shaunaka and other Sages from whom I received the knowledge of this Shastra. I have narrated the same Jyotish Shastra which I learnt from them. Do not impart the knowledge of this Shastra to one who is insignificative, slanders or calumniates others, is not intelligent, is wicked and unknown to you. Teach this supreme Vedanga Jyotish Shastra (Science of Astrology) only to one who is gentle and amiable, devoted, truthful, brilliant, and well known to you.
