Phaladeepika
तत्कालेन्दुद्वादशांशे मेषात्तावति भेऽपि वा । तस्मात्तावति भे वापि जन्मचन्द्रं वदेद्बुधः ॥ ३३॥
Find the exact Dwadasamsa of the Moon at the time of the Adhana and the Rasi to which it belongs. Count from (Mesha or from) this sign as many Rasis as the number represented by the Dwadasamsa in question. When the Moon is in the Rasi thus found in the month of delivery, the birth of the child in the womb may be expected.
