Phaladeepika
कालस्य फेनं तनुरुद्रदिव्यं वन्द्यो नटस्तैरनुसूर्यवारात् एषां समं मान्दिवदेव तत्त न्नाड्या स्फुट लग्नवदत्र साध्यम् ॥ ४॥
The position of Kala on the week days counting from Sunday onwards is at the end of Ghatikas 2, 26, 22, 18, 14, 10 and 6 respectively during day time. These figures have, as already stated for Mandi, to be proportionately altered and their exact positions determined as in the case of the Lagna.
