Quietness of mind in Yoga

Q: Learning languages makes the mind active. Does not the Yoga mean to keep the mind quiet and turn it always to the Divine?

Do you mean to say that in order to have quietness of the mind one must do nothing? Then neither the Mother nor I nor anyone else here has a quiet mind. Doing nothing with the mind is not quietude or silence. It is inactivity that leaves the mind thinking mechanically and discursively instead of concentrating on an object – that is all. Keeping the mind without occupation is not the same thing as peace or silence.

– Sri Aurobindo
