According to Desikachar's translation: "In the 1960s only two [Sanskrit] versions of this valuable text were available [Bombay Branch of the Royal Asiatic Society (BBRAS) and Trivandrum editions], and both were incomplete or inaccurate. He [Krishnamacharya] took the pains of writing the whole manuscript." Desikachar further states in his introduction: "However many verses of this twelve-chapter text are missing in both versions... He [Krishnamacharya] even corrected those manuscripts that were incomplete." In The Heart of Yoga, Desikachar indicates: "There is one critical edition of the Yoga Yājñavalkya written by Śrī Prabhad [sic] C. Divanji [BBRAS edition]."
