Next, finding the passed and coming parts of the first period lord. The remainder after dividing by five, 1;6, is called the passed part. Five less this, 3;54, is called the coming part. Then the passed part, 1;6, is multiplied by gomutrika (cross-wise multiplication) with a seventh of the year, 51;25;42;51;25. Each place is carried up by sixty. This gives 56;34;17;5;33;30. Divided by five, it gives 11;18;51;25;42;42. This is the first period lord's passed part, in days and so on. Then the coming part, 3;54, is multiplied by a seventh of the year and carried up. This gives 200;34;17;8;31;30. Divided by five, it gives 540;6;51;25;42;18. This is the first period lord's coming part, in days and so on. Here, the current kalahora (planet ruling the hour) lord has the first period, equal to the coming part. Then, in kalahora order, the others have periods of a seventh of the year. Then, at the end, when the year closes, the current kalahora lord has a period again. It equals the passed part.
Simple meaning: Kalahora example: the first lord gets about 40 days at the start and about 11 days at the end. The others get a seventh of the year each.
एवं मासप्रवेशकालयोरन्तरसप्तमांशमिता मासप्रवेशहोरेशादिदशा ज्ञेया ॥ तथैव दिनप्रवेशे होरेशादितो दिनप्रवेशकालयोरन्तरसप्तमांशमिता घटिकादिदशा दिनप्रवेशे ज्ञेया ॥ अत्रापि वर्तमानहोरेशस्य गतगम्यम्पूर्ववत् साध्यमिति ॥
Kalahora periods in the month and day: each lord gets a seventh of the month or day, starting from the hour lord then.
अथ देवकीर्तिमतेन वर्षप्रवेशादौ हद्दादशा ताजिकमुक्तावल्याम् ॥
Hadda periods: in the year, each hadda's degrees times 12 give days. In the month the degrees are days; in the day, doubled degrees are ghatikas.
लग्नेंकग्रहहद्दांशभुक्तभोग्यांशसंगुणा॥
Hadda periods: the lagna's hadda lord's period is split into passed and coming parts by its degrees.
