बृहत्संहिता (आचार्य वराहमिहिर - स्थापत्य, खगोल, मौसम व जल विज्ञान)

24 बृहत्संहितायाम् [Adh. III. Sl. 8-11
Sloka 7.—There are 33 Ketus, the sons of Rahu, and
are named Thamasa Keelakas. When they appear in the
Sun’s disc, their effects should be predicted according to
their colour, position and form.
ते चार्कमण्डलगताः पापफलाश्चन्द्रमण्डले सौम्याः ।
ध्वाङ्क्षकबन्धप्रहरणरूपाः पापाः शशाङ्केऽपि ॥८॥
Sloka 8.—And these Thamasakeelakas when they
enter the Sun’s disc produce malefic effects. The effects
will be auspicious when they enter the Moon’s orb. When
they assume the forms of a crow, a truncated body, a
sword, etc., they produce inauspicious effects even in the
Moon’s disc. Much worse will be the effect they produce
when they are in the Sun’s disc.
तेषामुदये रूपाण्यम्भः कलुषं रजोवृतं व्योम ।
नगतरुशिखरमर्दी सशर्करो मारुतश्चण्डः ॥९॥
ऋतुविपरीतास्तरवो दीप्ता मृगपक्षिणो दिशां दाहाः ।
निर्घातमहीकम्पादयोभवन्त्यत्र चोत्पाताः ॥१०॥
Slokas 9-10.—When they become visible, the follow-
ing indications appear : the water will become muddy
and foul ; the sky will be filled with dust ; there will
arise storms carrying sand with them and crushing tops of
mountains and trees ; the trees and creepers will reveal
effects contrary to the seasons ; the animals and birds
will become heated by the Sun ; there will be false fires
in all the directions ; there will be thunderbolts, earth-
quakes and such unusual phenomena boding calamity.
• न पृथक् फलानि तेषां शिखिकीलकराहुदर्शनानि यदि ।
तदुदयकारणमेषां केत्वादीनां फलं ब्रूयात् ॥११॥
Sloka 11.—The effects described above, viz., water
becoming turbid, etc. are not to be attributed to the
