Visual focus can be improved by positioning screens at or slightly above eye level, as this activates brain circuits associated with alertness.

“Contrary to what most people do, which is to look down at their laptop, tablet, or phone, if you want to be alert and you want to maintain the maximum amount of focus for whatever it is that you're reading or doing, you want that screen or whatever it is that you're looking at to at least be at eye ”

Practitioners can train themselves to become masters of their thought processes by systematically applying techniques to avoid unwholesome thoughts.

“One will think whatever thought one wishes to think and one will not think any thought one does not wish to think.”
