Dear Sir,

We are thankful to Tin and Wiwanitkit for their observation [1] on our article "effect of trataka on cognitive functions in the elderly." [2]

In response to their observation, we would like to quote that authentic traditional texts of yoga describe the benefits of trataka on a whole range of physiological and cognitive functions. [3],[4] Physiologically trataka relieves various eye ailments such as eye strain and headache, myopia, astigmatism, glaucoma [5] and even early stages of cataract. [6] There are different methods of practicing trataka serving different purposes. Different objects of awareness are used in the practice of trataka, depending on the purpose of practicing or taking condition of a subject practicing into consideration. Certain practices are to be done only under guidance, such as sun trataka if not done properly can damage the retina or can lead to other eye ailments.

The trataka procedure used in this study has been developed and used by Swami Vivekananda Yoga Anusandhana Samasthana for the past many years and has found to be effective with nil adverse effects. The procedure was thus further modified to suit elderly individuals in our study where time of gazing at the flame was only 10 s to begin with, which was gradually increased to 1-2 min; there were different components including focusing, defocusing, internal focusing, with sufficient relaxation in between to reduce possible strain to the eyes. Within 7 days, subjects reported having reduced eyestrain, and no any adverse effects were noted. Similar positive effects of trataka along with other yoga practices have been shown to reduce visual strain in persons with progressive myopia. [7]

Thus, the trataka practice can be modified depending on the error of refraction. The authors would thus like to state that the trataka procedure as used in this study is feasible, safe and can be practiced by the elderly without worsening their eyesight problems.
