Adh. XI. Sl. 1-5] एकादशोऽध्यायः 127
केतुचारः ॥११॥ Ketu.
गार्गीयं शिखिचारं पाराशरमसितदेवलकृतं च ।
अन्यांश्च बहून् दृष्ट्वा क्रियतेऽयमनाकुलश्चारः ॥१॥
Sloka 1.—Having comprehended the peculiarities
of Ketu's transit as treated of by sages Garga, Parasara,
Asita, Devala and many others, I expound the same in
the most unambiguous manner.
दर्शनमस्तमयो वा न गणितविधिनास्य शक्यते ज्ञातुम् ।
दिव्यान्तरिक्षभौमास्त्रिविधाः स्युः केतवो यस्मात् ॥२॥
Sloka 2.—It is not possible to find out by calculation
the rising or setting of Ketu, inasmuch as there are three
sorts of Ketus, viz., celestial, atmospheric and terrestrial.
अहुताशेऽनलरूपं यस्मिंस्तत्केतुरूपमेवोक्तम् ।
खद्योतपिशाचालयमणिरत्नादीन् परित्यज्य ॥३॥
Sloka 3.—In places where, though there is no fire,
there is still an igneous appearance, Ketu's presence is
recognised except where there are glow-worms, phos-
phoric lights on graves, gems, jewels and the like.
ध्वजशस्त्रभवनतरुतुरगकुञ्जराद्येष्वथान्तरिक्षास्ते ।
दिव्या नक्षत्रस्था भौमाः स्युरतोऽन्यथा शिखिनः ॥४॥
Sloka 4.—The atmospheric Ketus are such as are
seen on flagstaffs, weapons, houses, trees, horses, ele-
phants and the like ; the celestial ones are those that
are seen among the asterisms. Such as do not belong
to the above two categories are to be known as terrestrial
Ketus.
शतमेकाधिकमेके सहस्रमपरे वदन्ति केतूनाम् ।
बहुरूपमेकमेव प्राह मुनिर्नारदः केतुम् ॥५॥
