सारावलीमुडुदशां च वराहहोरा- मालोक्य जातकफलं प्रवदेन्नराणाम् । प्रश्नोदयग्रहवशादथ वा स्वजन्म- राश्यादिना वदतु नास्त्यनयोर्विशेषः ॥ ६३॥
In the case of a nativity, one ought to guess the effects after a reference to Saravali, Varahamihira's Hora Sastra and the Nakshatra Dasa. While so guessing, one must refer also to the positions of the planets with reference to the Lagna at the time of the query or the Janma Rasi or Lagna at birth and then attempt his predictions. any material difference between the There will not be Prasna Lagna and the Janma Lagna. (in the matter of the predictions.)
