6.12 Pratisthapya, having established; sthiram, firmly; sucau, in a clean; dese, place, which is solitary, either naturally or through improvement; atmanah, his own; asanam, seat; na ati ucchritam, neither too high; na ati nicam, nor even too low; and that made of caila-ajina-kusa-uttram, cloth, skin, and kusa-grass, placed successively one below the other-the successive arrangement of cloth etc. here is in a reverse order to that of the textual reading-. What follows after thus establishing the seat? Upavisya, sitting; tatra, on that; asane, seat; yogam yunjyat, he should concentrate his mind. To what purpose should he concentrate his mind? In answer the Lord says: atma-visuddhaye, for the purification of the internal organ. How? Krtva, making; manah, the mind; ekagram, one-pointed,by withdrawing it from all objects; and yata-citta-indriya-kriyah, keeping the actions (kriyah) of the mind (citta) and senses (indriya) under control (yata). The external seat has been spoken of. Now is being stated how the posture of the body should be:
6.12 See Comment under 6.15
6.11 - 6.12 In a clean spot, i.e., in a spot pure in itself, not owned or controlled by impure persons and untouched by impure things; having established a firm seat, a seat made of wood or similar material, which is neither too high nor too low; which is covered with cloth, deer-skin and Kusa grass in the reverse order; seated on it in a way which promotes the serenity of mind; having the mind concentrated on Yoga; and holding the activities of the mind and senses in check in all ways - he should practise Yoga, i.e., practise the vision of the self for the purification of the self, i.e., to end his bondage.
