To think with a one-track mind of winning is a sickness.
To think with a one-track mind of martial arts is a sickness.
To think with a one-track mind of displaying what one has learned is a sickness, as is thinking only of Attacking or only of Waiting.
To think obsessively about getting rid of sickness is also a sickness.
To fixate the mind on any single thing is considered a sickness.
All these various sicknesses exist in the mind.
Therefore, one must temper the mind to be rid of them.
