दशानयनाधिकाराध्यायः
यावर्तमानास्य तु भस्य भुक्तिः सा तद्भभक्तैष्यघटी विनिघ्ना॥भाज्याथ तद्भस्य गतैष्यनाडी योगेन लब्धो गतगम्यके ते ॥ ४ ॥
Take the share of the star now running. Multiply it by that star's ghatikas (24-minute units) gone, and again by those still to come. Divide each by the star's ghatikas gone and to come added together. The results are the part gone and the part to come.
Simple meaning: Balarama's periods: split the running star's share by how much of the star has gone and how much is left.
युते विधेये गतगम्यभानां भुक्त्या दिनाद्ये गतगम्यके स्तः ॥
Balarama's periods: the first lord's remaining part opens the year. The others follow. The first lord's gone part closes it.
उदाहरणम् ॥ वर्षप्रवेशे पुष्यनक्षत्रन्तेनादौ सूर्यदशा जाता दिनाद्या २०॥ अथेयं दशा चतुर्नक्षत्रेशा अतो दशादिनानि चतुर्भुक्तानि लब्धा ५ एकैकनक्षत्रस्य दिनाद्या भुक्तिः ॥ अथ पुष्यनक्षत्रस्य भुक्तघटीभि १२ र्भस्य भुक्ति ५ र्गुणिता ६० सर्वर्क्षघटी ६० भक्ता लब्धा पुष्यस्य गता भुक्तिर्दिनात्मिका १ ॥
Balarama's periods, example: year entry in Pushya, Sun first with 20 days. Each star 5 days. 12 of 60 ghatis gone gives 1 day gone.
अथगौरीमतदशासुग्रहाणामंतर्दशाचक्रं योगः ॥
Gauri's mudda sub-periods: for each planet's days, each sub-period is its days times the multiplier, divided by 60.
