“To find the perpendicular लम्बं, put an assumed chord कल्पितज्या equal to half the chord पूर्णज्यार्द्धं of the (inscribed) tetragon; find its arrow in the manner aforesaid, and subtract that from the arrow of the chord तत्रिभुजस्यशर of the (inscribed) triangle, the remainder is the perpendicular. लम्बपरिमाणं । Thus the perpendicular लम्बं comes out 21,989: it is the side of a rectangular triangle. The third part of the inscribed एकजात्य त्रिभुजं triangle is 34,641: it is the upright. कोटि । The square root of the sum of their squares वर्गयोग मूलं is 41,031: and is the side of the inscribed nonagon.” वृत्तस्य​नवभुजं । [Illustration: THE OM TAT SAT.] YOGA VÁSISHTHA. BOOK I. ON MORAL APATHY CHAPTER I. INTRODUCTION. SECTION I. DIVINE ADORATION _Hail The Eternal._ Om, salutation to the self-same Reality, from whom all beings proceed, by whom they are manifest, upon whom they depend, and in whom they become extinct (in the end). 2. He is the knower, the knowledge and all that is to be known. He is the seer, the (act of) seeing, and all that is to be seen. He is the actor, the cause and the effect: therefore salutation to Him (who is all) knowledge himself. 3. Salutation to Him (who is) supreme bliss itself, from whom flow the dews of delight (as water springs from a fountain) both in heaven and earth, and who is the life of all. SECTION II. NARRATIVE OF SUTÍKSHNA. 4. One Sutíkshna, a Bráhmana, whose mind was full of doubts, went to the hermitage of Agasti and asked the sage respectfully:— 5. Oh great sage! that art informed in all the ways and truths of virtue, and knowest with certainty all the Sástras, I am in a great doubt (about something) which I pray you will kindly remove. 6. Tell me whether a man’s acts or his knowledge or both of these, is in your opinion, the cause of his emancipation. 7. Agasti replied:— As the flight of birds in the air is effected by means of both their wings, so the highest state of emancipation is attained through the instrumentality of both knowledge and acts. 8. It is neither our acts nor knowledge alone that produces emancipation, but both together are known as the means of it. SECTION III. ANECDOTE OF KÁRUNYA. 9. I will recite to you an instance on this subject from the old traditions, relating a Bráhman named Kárunya, who was learned in the Vedas in days of yore. 10. He was the son of Agnivesya and accomplished in the Vedas and all their branches, and after finishing his studies at the preceptor’s, returned to his own abode.
