By working the āsanas, by putting fortheffort, many of the inside poisons and toxins come out, and the body ispurified. We should rub our sweat into the skin, not off of the body. He said some āsanas are slippery and we might have a towel but not to usea towel too often to wipe sweat. The sweat created from practice is not“easy” sweat, meaning sweat created by heating the room like in hot yoga. The sweat we create through our efforts is beneficial if rubbed back intothe skin. Ultimately, through this āsana practice, we are working towardthe point where this physical body doesn’t bother us. When sitting forPrāṇāyāma, we can be in Padmāsana for a long time without disturbing the mindwith the body.
One student asked if Kriyā (cleansing)techniques were for practitioners. Sharath said that they are used only whena person has a particular problem. We are doing āsanas and cleansing isalready happening. There is no need to perform a kriyā unless somethingis wrong. For example, sūtra neti, threading string through the nostriland mouth, may be beneficial for a particular allergy or infection. Ifthere is no sinus infection, jala netī, or the use of a netī pot, mayprovide relief of congestion. Naulī can be used for incorrect digestionbut should be used carefully. Women, especially, can find it hard on the reproductiveorgans. These techniques were for sadhus with no family and before therewere no hospitals. People had to treat themselves. He stressed weshould be educated about what we are doing. The technique can affect usin a different way then intended if we do it and have no problem. TrāṭakaKriyā, gazing at one fixed point, usually a flame, can be done to improve ourconcentration in addition to helping certain eye problems. It is safe todo regularly. Referring back to sinus troubles and sickness, Sharathreminded us to not practice with fever or a very bad cold because we likelyaren’t getting enough air during the practice or we get too heated. Headded with a chuckle that you’ll only make everyone in the shala sick, too.
