Trataka is a. deceptively simple but powerful practice. Trataka means 'to gaze steadily at a fixed point' and there are two forms of the practice. One is 'bahiranga' or external trataka and the other is 'antaranga' or internal trataka. Bahiranga is easier to practise because one simply has to gaze at an object or symbol. However, antaranga trataka involves clear and stable inner visualisation of an object.
In the practice of trataka an object is gazed at until its subtle form manifests in front of the closed eyes. The point of concentration is usually a symbol or object which activates the inner potential and can absorb the mind. The symbol most commonly used is a candle flame, because even after the eyes are closed, the impression remains naturally for some time, and then antaranga trataka can easily be performed. The purpose of focusing the eyes on an external object is to arouse the internal vision and make it absolutely steady by stopping the eye movements.
Trataka is a process of concentrating the mind and curbing its oscillating tendencies. The one-pointed concentration of mind is termed 'ekagrata'. There are numerous distractions which obstruct ekagrata. Association and identification through the eyes and sight are major contributing factors to this leakage. Furthermore, the eyes move constantly, either in large movements (saccades), or tremors (nystagmus).
Even when the eyes are focused on an external object the perception is always fluctuating due to these spontaneous movements. When the same object is constantly seen, the brain becomes accustomed or habituated, and soon stops registering that object. Habituation coincides with an increase of alpha waves indicating diminished visual attention to the external world. When alpha waves are produced it indicates that particular areas of the brain have ceased functioning. This is the case, not only with trataka, but with any practices of concentration. When the awareness is restricted to one unchanging sense stimulus, like touch or sound, the mind is 'turned off'. Complete absorption in a single perception induces withdrawal of contact with the external world.
Benefits
According to the 'Hatha Yoga Pradipika' of Swatmarama, 'Trataka eradicates all eye diseases, fatigue and sloth and closes the doorway creating these problems. It should carefully be kept secret like a golden casket." Trataka benefits not only the eyes but a whole range of physiological and mental functions. It is therapeutic in depression, insomnia allergy, anxiety, postural problems, poor concentration and memory.
Trataka unlocks the inherent energy of the mind and channelises it to the dormant areas of the unconscious. Yogi Swatmarama mentions the arousal of clairvoyance but other capacities such as telepathy, telekinesis, psychic healing, etc., can develop.
Not only that, further results of one-pointedness of mind are strong willpower, improved memory and concentrative ability. Physiologically, trataka relieves eye ailments such as eye strain and headache, myopia, astigmatism and even early stages of cataract. The eyes become clear bright, able to see the reality beyond appearances.
