For it imitates² the mirror and is not seen even when the face is there (but the mirror is removed). द्वयोरेवेति चेत्तन्न द्वयोरेवाप्यदर्शनात् । अदृश्यस्य सतो दृष्टिः स्याद्राहोश्चन्द्रसूर्ययोः ॥ ३९ ॥ 39. (First line). If you say that it is the property of both, we say 'No'; because it is not seen even when both are present (but improperly placed). (Second line). (Objection). It may be said that Râhu, a real thing, though invisible, is (sometimes) seen³ in the sun and moon; (so the reflection of the face, a reality, though invisible, is sometimes⁴ seen in the mirror). राहोः प्रागेव वस्तुत्वं सिद्धं शास्त्रप्रमाणतः । छायापक्षे त्ववस्तुत्वं तस्य स्यात्पूर्वयुक्तिः ॥ ४० ॥ 40. (Reply). That Râhu is a real⁵ thing is known from the scriptures⁶ before one sees it in the sun or moon. But according to those who hold that it is the shadow of the earth it cannot be a real thing and the unreality of the reflection has been proved by arguments before.⁷ ¹ That is, the reflection of the face. ² I.e., undergoes changes that the mirror is subject to. ³ During eclipses. See footnote 4, verse 34, Ch. 17. ⁴ When a mirror is properly placed. ⁵ See footnote 4, verse 34, Ch. 17. ⁶ But there is no such evidence with regard to the existence of the reflection. ⁷ Verses 37-39 above.
