Word origin · etymology

Sanskrit numerical compound: daśāṃśa.

Daśa means ten and aṃśa a portion: the tenth-part name. The first element is the number daśa, not the separate word daśā used for a state or planetary period.

How we know · epistemology

Tenth-part mapping convention

The chart transforms D1 inputs under a declared division rule. A change in source data or method can change the result. Interpreting that result as a work theme is a further traditional step, not an astronomical observation of a second sky.
