ConZentrate helps to improve the focus of the mind.Conzentration app makes it
a fun event by setting goals that you can achieve and at the same time allowing you improve your concentration.
The original name for this technique is called as Trataka in Sanskrit.
Patanjali's Yoga Sutras mentions this as "Ekatattva Abhayasa". It means the practise of One reality. Trataka is the
fixing of one's gaze, either externally or internally, on a point of attention. Together with this process,
a breathing exercise may have to be practiced to calm the disturbances in the mind.
