O best of the twice-born, I shall now narrate the results of the house of longevity: when the lord of the house of longevity occupies a kendra, he bestows long life upon the native.
If the lord of the house of longevity stands there itself in the company of malefics, the native is made short-lived; the same result follows when the ascendant lord is similarly placed.
Verse 4 — Judging Longevity through Saturn and the Tenth Lord
एवं हि शनिना चिन्ता कार्या तर्कैर्विचक्षणैः ।
कर्माधिपेन च तथा चिन्तनं कार्यमायुषः ॥ ३॥
evaṃ hi śaninā cintā kāryā tarkairvicakṣaṇaiḥ | karmādhipena ca tathā cintanaṃ kāryamāyuṣaḥ || 3||
In this manner, Saturn should indeed be examined by astute reasoners through sound logic, and deliberation on longevity must likewise be carried out through the lord of karma (the tenth lord).
Verse 5 — Sixth and Twelfth Lords Yielding Long Life
When the sixth lord occupies the sixth or the twelfth, or the twelfth lord stands in the sixth or the twelfth—or either of them is placed in the ascendant or the eighth—he bestows long life.
Verse 6 — Lagna and Eighth Lords in Own, Friendly or Exalted Signs
The ascendant lord—and again the eighth lord—placed in its own sign, its own amsa, a friendly sign or a sign of exaltation, certainly produces long life.
Verse 7 — Lagna, Eighth and Tenth Lords in Angles or Trines
लग्नाष्टमपकर्म्मेशमन्दाः केन्द्रत्रिकोणयोः ।
लाभे वा संस्थितास्तद्वद् दिशेयुर्दीर्घमायुषम् ॥ ६॥
Likewise, the lords of the ascendant, the eighth and the tenth, when situated in the kendra or trikona houses, or in the eleventh, indicate long life in the same way.
