Swami Mukundananda
Why can't I make my mind focus, and how can I do it when it matters?
When the intellect is convinced, it controls the mind
A child who says the mind doesn't like to study can still bring the mind under control for two hours in the final exam, because the intellect was convinced about the gravity of the situation. Then it exerted its power and control.
The same child, when going for the final exam at the end of the year, brings the mind under control for two hours.
