 In terms of comparative textual chronology, states Larson, the final redaction of Yogasutra and the writing of Samkhya-karika were probably contemporaneous.The Samkhya literature grew with later developments such as through "Bhashya" on Samkhya karika in the 9th-century "Samkhya Tattva Kaumudi" of Vacaspati Mishra.The "Karika", wrote ancient Hindu scholars Gaudapada and Vacaspati Misra, contains seventy two verses.
