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

60 बृहत्संहितायाम् [Adh. V. Sl. 47-50
Sloka 46.—When a third or a fourth part of the disc
or even half is concealed (by darkness), it is called ग्रसन
(Grasana); a flourishing king will suffer loss of wealth
and countries which are thriving and prosperous will
suffer devastation.
पर्यन्तेषु गृहीत्वा मध्ये पिण्डीकृतं तमस्तिष्ठेत् ।
स निरोधो विज्ञेयः प्रमोदकृत् सर्वभूतानाम् ॥४७॥
Sloka 47.—When Rahu eclipses the disc all round
leaving a lump of thick darkness in the middle, it is called
निरोध (Nirodha). The effect of this will be that all crea-
tures will be happy.
अवमर्दनमिति निःशेषमेव सञ्छाद्य यदि चिरं तिष्ठेत् ।
हन्यात्प्रधानभूपान् प्रधानदेशांश्च तिमिरमयः ॥४८॥
Sloka 48.—When Rahu conceals the entire orb and
is in that position for a considerably long period, it is
called अवमर्दन (Avamardana) and the result of it will be
the destruction of leading kings and important countries.
वृत्ते ग्रहे यदि तमस्तत्क्षणमावृत्य दृश्यते भूयः ।
आरोहणमित्यन्योन्यमर्दनैर्भयकरं राज्ञाम् ॥४९॥
Sloka 49.—If soon after the termination of the
eclipse, the luminary be again enveloped in darkness, it is
called आरोहण (Arohana); there will be mutual strife among
kings causing great fear and anxiety.
दर्पण इवैकदेशे सबाष्पनिःश्वासमारुतोपहतः ।
दृश्येताऽऽघ्रातं तत् सुवृष्टिवृद्ध्यावहं जगतः ॥५०॥
Sloka 50.—The eclipse is known as आघ्रात (Aghrata)
when it appears on a part of the disc like a mirror filled
with the vapour of hot breath when blown on it; and it
indicates timely rains and prosperity to the people.
