6.12. Sitting there on the seat and making the mind single-pointed, let him, with the activities of his mind and senses subdued, practise Yoga for self-purification.
Shri Purohit Swami
6.12 Seated thus, his mind concentrated, its functions controlled and his senses governed, let him practise meditation for the purification of his lower nature.
Sri Abhinav Gupta
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.
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 There, sitting on the seat, with the mind concentrated and holding the mind and senses in check, he should practise Yoga for the purification of the self.
6.12 (and) sitting on that seat, he should concentrate his mind for the purification of the internal organ, making the mind one-pointed and keeping the actions of the mind and senses under control.
6.12 There, having made the mind one-pointed, with the actions of the mind and the senses controlled, let him, seated on the seat, practise Yoga for the purification of the self.
6.12 तत्र there? एकाग्रम् onepointed? मनः the mind? कृत्वा having made? यतचित्तेन्द्रियक्रियः one who has controlled the actions of the mind and the senses? उपविश्य being seated? आसने on the seat? युञ्ज्यात् let him practise? योगम् Yoga? आत्मविशुद्धये for the purification of the self.Commentary The self means the mind. The real Supreme Self is the Atma. This is Primary (Mukhya). Mind also is the self. But this is used in a secondary sense (Gauna). Mukhya Atma is Brahman or the highest Self. Gauna Atma is the mind.Make the mind onepointed by collecting all its dissipated rays by the practice of Yoga. Withdraw it from all senseobjects again and again and try to fix it steadily on your Lakshya or point of meditation or centre. Gradually you will have concentration of the mind or onepointedness. You must be very regular in your practice. Only then will you succeed. Regularity is of paramount importance. You should know the ways and habits of the mind through daily introspection? selfanalysis or selfexamination. You should have a knowledge of the laws of the mind. Then it will be easy for you to check the wandering mind. When you sit for meditation? and when you deliberately attempt to forget the worldly objects? all sorts of worldly thoughts will crop up in your mind and disturb your meditation. You will be ite astonished. Old thoughts that you entertained several years ago? and old memories of past enjoyments will bubble up and force the mind to wander in all directions. You will find that the trapdoor of the vast subconscious mind is opened or the lid of the storehouse of thoughts within is lifted up and the thoughts gush out in a continous stream. The more you attempt to still them? the more they will bubble up with redoubled force and strength.Be not discouraged. Nil desperandum. Never despair. Through regular and constant meditation you can purify the subconscious mind and its constant memories. The fire of meditation will burn all thoughts. Be sure of this. Meditation is a potent antidote to annihilate the poisonous worldly thoughts. Be assured of this.Meditation on the immortal Self will act like a dynamite and blow up all thoughts and memories in the conscious mind. If the thoughts trouble you much? do not try to suppress them by force. Be a silent witness as in a bioscope. They will subside gradually. Then try to root them out through regual silent meditation.During introspection you can clearly observe the rapid shifting of the mind from one line of thought to another. Herein lies a chance for you to mould the mind properly and direct the thoughts and the mental energy in the divine channel. You can rearrange the thoughts and make new associations on a new Sattvic basis. You can throw out wordly and useless thoughts. Just as you remove the weeds and throw them out? you can throw these out? and you can cultivate sublime? divine thoughts in the divine garden of your mind. This is a very patient work. This is a stupendous task indeed. But for a Yogi of determination who has the grace of the Lord and an iron will it is nothing.Calm the bubbling emotions? sentiments? instincts and impulses gradually through silent meditation. You can give a new orientation to your feelings by gradual and systematic practice. You can entirely transmute your wordly nature into divine nature. You can exercise supreme control over the nervecurrents? muscles? the five sheaths (of the Self)? emotions? impulses and instincts through meditation.
