The lord of the 8th, or a planet placed in the 8th and afflicted by malefics, becomes an arishta-kāraka; one situated in a maraka sthāna surely brings about death.
Verse 2 — Eight Years of Balarishta and the Span of Life
Eight years at the outset constitute balarishta; yogarishta they declare to be twenty; alpāyu is thirty-two, madhyamāyu up to seventy, and full life extends to a hundred years.
Verse 3 — Saturn, Mars and Sun as Death Inflicters
एकत्र मन्दावनिनन्दनार्का रन्ध्रस्थिता वा रिपुराशियाताः । सौम्यैरयुक्ता अविलोकितास्ते जातस्य सद्यो मरणप्रदाः स्युः ॥
Saturn, Mars and the Sun joined together, or placed in the eighth, or gone to an enemy sign without benefic association or aspect — these inflict immediate death upon the native.
If the Moon occupies the lagna, sixth, eighth or twelfth, aspected by malefics without benefic aspect, and the kendras lack benefics, the born one departs from his vital breaths.
Verse 5 — Waning Moon in the 12th Brings Speedy Death
kṣīṇe himagau vyayage pāpair udayāṣṭamagaiḥ | kendreṣu śubhāśca na cet kṣipraṃ nidhanaṃ pravadet ||
When the waning Moon sits in the twelfth with malefics occupying the ascendant and the eighth, and benefics are absent from the kendras, speedy death is foretold.
