This verse shows that the text preserves traditional catalogues of substances—especially named gems—by citing them as carefully enumerated by expert authorities.
This specific verse is not about the soul’s journey; it is a classificatory listing of gems, indicating a descriptive/encyclopedic section rather than an afterlife narrative.
Use it as a reference point for accurate identification and study of traditional Sanskrit material categories (e.g., gems used in ritual, donation, or cultural practice), ensuring terminology is preserved correctly.
