Who among the following kings is described in an inscription as the Supreme Being, the cause of the prosperity of the good and the destruction of the bad?

The description of a king as the "Supreme Being" (Purusha) and the "cause of the prosperity of the good and the destruction of the bad" (sādhv-asādhu-udaya-pralaya-hetu-puruṣasya) is found in the Prayaga Prashasti (Allahabad Pillar Inscription). This inscription was composed by Harishena, the court poet of the Gupta Emperor Samudragupta.

The text portrays Samudragupta as a divine figure, equating him with gods like Kubera (wealth), Varuna (ocean/justice), Indra (heavens), and Yama (death). It emphasizes his role as a protector of the righteous and a punisher of the wicked, a common theme in Gupta-era political ideology which sought to deify the monarch. Other kings like Gautamiputra Shatakarni are praised in inscriptions (e.g., Nashik Prashasti) for their valor and lineage, but the specific phrasing regarding the "Supreme Being" as the cause of prosperity and destruction is unique to the eulogy of Samudragupta.
