Vācaspati Miśra, a scholar of the Vedanta school of Hinduism, in his bhasya on the Yogasutra's 3.30 wrote, "Whatever the yogin desires to know, he should perform "samyama" in respect to that object". Moksha (freedom, liberation) is one such practice, where the object of "samyama" is Sattva (pure existence), Atman (soul) and Purusha (Universal principle) or Bhagavan (God). Adi Shankara, another scholar of the Vedanta school of Hinduism, extensively commented on "samyama" as a means for "Jnana-yoga" (path of knowledge) to achieve the state of "Jivanmukta" (living liberation).
