தீர்மானம் - பிருஹத் பராசர ஹோர சாஸ்திரம்

1-4. Maharishi Parasara said. O Brahmin! I have described to you the Jyotish 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, nor to one, who is not intelligent, is wicked and unknown to you. Teach this supreme Vedanga Jyotish Shastra only to one, who is gentle and amiable, devoted, truthful, brilliant and well known to you.

5-6. Only that person, who possesses adequate knowledge of time and the positions of Grahas and Nakshatras, can understand this Hora Shastra. Only that person, who has complete knowledge of the Hora Sastra and who is truthful, can make correct favourable, or unfavourable predictions.
