Word origin · etymology

Sanskrit numerical compound: ṣaṣṭyaṃśa.

Ṣaṣṭi means sixty and becomes ṣaṣṭy before a following vowel; aṃśa means a portion. The result is the sixtieth-part name, distinct from ṣaṣṭha, meaning sixth.

How we know · epistemology

Sixtieth-part mapping and belief-dependent interpretation

Half-degree source portions make boundary and birth-time uncertainty material. A reproducible sign assignment cannot demonstrate a former life, karma or moral desert. Sign counting and the ordering of traditional portion names are separate conventions.
