Focus & willpower
Attention works like a muscle: it gets stronger when you use it and scatters when you don't. In this practice you look at a single point on the screen, and when your mind goes elsewhere, you bring it back. It sounds simple. In the first two minutes you'll see how hard it is.
The method is known in the yoga tradition as trataka. The fifteenth-century text Hatha Yoga Pradipika lists it as one of the six cleansing practices. Traditionally you gaze at a candle flame; here four different visuals take the place of the flame.
People who do this regularly for a few weeks often say the same thing: when they start a task, they notice the urge to reach for their phone sooner. Noticing is half of resisting.
Small studies on trataka report improvements on attention tests, but the samples are small and the results are not conclusive. Think of it not as a brain-boosting technique but as a plain exercise for training your attention.
I decide where my attention goes. When it drifts, I'll bring it back. That's all.
If your eyes burn or water, close them, rest, and then continue. Forcing it until it hurts does no good.
Moving and rotating visuals can make some people dizzy. If you have a history of epilepsy or are sensitive to light, skip this practice.
If you wear contact lenses, your eyes dry out faster, so keep the sessions short.
Note: The practices here are for rest and for coming back to yourself. They are not medical advice, diagnosis or treatment. If you have a health condition or take medication, follow what your doctor tells you. If you feel unwell during a practice, stop.
