230 A THOUSAND TEACHINGS [CHAP. XVIII
38. If it is argued that it¹ is a property of the face
because it¹ is called after it, that cannot be so. 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.
