Describing the chariot that bears human soul as frugal is an example of paradox epiphany?

Yes, describing the chariot that bears the human soul as frugal is an example of paradox epiphany. Paradox epiphany is a figure of speech that combines two seemingly contradictory ideas or concepts to create a new and deeper understanding of a subject. In this case, the frugal nature of the chariot carrying the human soul suggests that the soul's journey is not about material wealth or possessions but about spiritual growth and self-discovery.
