Kriyas are special cleansing techniques in Hatha Yoga to prepare body for effective pranayama and meditation. Primary purpose of Kriya is to make clear channel for the energy to flow in right direction.
Before soul and mind can be purified it is necessary to purify body. Six kriyas were developed in order to purify body from various impurities. Kriyas are used by shadhaka for purifying the body and by common people for curing certain diseases related to certain organs or body systems. For example Neti can be used for sinus, Trâtaka for eye, concentration and will power.
According to Ayurveda all disease generate because of imbalance kapha(mucus), pitta(bile) and vata(wind). Kriyas are used to bring balance in three to stay healthy. Literature says that if there is perfect balance of imbalance kapha(mucus), pitta(bile) and vata(wind) in body then there is NO need to practice Kriyas. Each Kriya must be performed based on need of shadhaka. For example if nose is blocked Neti would be wise to practice, if there is acidity in stomach dhauti would be wise to practice.
