 In contrast, verse seventy two of the surviving 6th-century CE "Karika" declares that its original had just seventy verses, implying that a more ancient version of Samkhya-karika once existed.Scholars have attempted to produce a critical edition, by identifying the most ancient original set of seventy verses, but this effort has not produced a consensus among scholars.In terms of content, importance and meaning, the text is essentially the same regardless of which version of the manuscript is referred to.
