Brihat Jataka
हित्वार्कं सुनफानफादुरुधुरा: स्वान्त्योभयस्थैर्ग्र है: शीतांशो: कथितोऽन्यथा तु बहुभि: केमद्रु मोऽन्यैस्त्वसौ ॥ केन्द्रे शीतकरेऽथवा ग्रहयुते केमद्रु मो नेष्यते केचित्केन्द्रनवांशकेषु च वदन्त्युक्तिप्रसिद्धा न ते ॥ १३-३ ॥
With the exception of the Sun; Sunapha, Anapha, and Durudhura are indicated with the planets situated in the 2nd, 12th, or both houses from the Moon, respectively. But otherwise, with the many others (combinations) is Kemadruma Yoga. But if that (a planet minus the Sun and Moon) is in an angle or when the Moon is joined to a planet, it is not to be sanctioned as a Kemadruma yoga. Some others say, (the Kemadruma is void when a planet) is in the navamsha portions of the angles. But those (exceptions) are not an authoritative statement.
