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

730 बृहत्संहितायाम् [Adh. XCVI. Sl. 12-13]
द्विमूर्त्तिसञ्ज्ञे तु वदेद्द्विनाम सौम्येक्षिते द्विप्रकृतौ च राशौ ।
यावान् गणः स्वोदयगोंशकानां तावान् ग्रहः संग्रहकेऽक्षराणाम् ॥६॥
6. In the case of a dual sign, two names will have to be
declared; when it is aspected by benefics, then too, the same
result. The particular Navamsa rising at the time, gives the
number of letters constituting the name.
संयोगमादौ बहुलेषु विन्द्यात् कूटेषु संयोगपरं वदन्ति ।
स्वोच्चांशके द्विष्कृतमृक्षयोगाद्गुर्वक्षरं तद्भवनांशके स्यात् ॥७॥
7. If the rising sign be odd, the name will begin with a
conjunct consonant ; if an even one, with a letter followed by a
conjunct consonant. When the planet (contributing a letter to
the name) is posited in his highest exaltation, the letter is repeated
according to the nature of the particular sign (odd or even); a
name will have a long syllable गुरु in the particular place signified
by the Navamsa rising at the time.
श्रीधर, क्षीर, स्मर are the examples for the first. पद्म, धर्म, वसुदत्त,
etc. for the second ; if odd. दरद, दामोदर, if even, देवदेव, धराधर etc.
मात्रादियुक् स्याद्ग्रहयुक्तिकोणे द्रेष्काणपर्यायवदक्षरेषु ।
नमोबलेषूर्ध्वमधोऽम्बुजेषु ज्ञेयो विसर्गोऽस्तबलान्वितेषु ॥८॥
8. When the 5th or the 9th house is occupied by planets,
there will be an extra syllabic instant in the name in the letter
signified by the decanate. When the 10th house is strong, there
will be the upper sign of long syllable ; when the 4th, lower sign ;
when the 7th, a Visarga.
शीर्षोदयेषूर्ध्वमुशन्ति मात्रामधश्च पृष्ठोदयशब्दितेषु ।
तिर्यक् च विन्द्यादुभयोदये तां दीर्घेषु दीर्घादितरेषु नान्यत् ॥९॥
9. When a Seershodaya Rasi is rising, the मात्रा (syllable
instant) will be upwards; when it is a Prishtodaya one, the
मात्रा will be downwards. In the case of a dual sign rising, it is
across; when it is a long sign, there is a long syllable; when
it is medium or short, it will be short.
