Ballanced Energy is neither Lazy, nor Restless!

Laziness overcomes one strong in concentration and weak in energy,
since concentration favours idle inaction...
Agitation and restlessness overpowers one strong in energy and weak
in concentration, because energy stimulate agitation...
But concentration coupled & ballanced with energy cannot lapse into laziness,
& energy coupled & ballanced with concentration cannot provoke
restlessness...
Therefore should these two
abilities be ballanced, since excellence of effort
and mental absorption arises out of the even ballancing of
the mental abilities.
