Dhammapada 33-34 [Khuddaka Nikaya]

3 - Cittavagga, The Mind 
1 - Meghiyatthera Vatthu

Phandanam capalam cittam,
durakkham dunnivarayam;
ujum karoti medhavi,
usukarova tejanam.
Varijova thale khitto,
okamokata ubbhato;
pariphandatidam cittam,
maradheyyam pahatave.

33: The mind is excitable and unsteady; it is difficult to control and to restrain. The wise one trains his mind to be upright as a fletcher straightens an arrow.
34: As a fish quivers when taken out of its watery home and thrown on to dry ground, so does the mind quiver when it is taken out of the sensual world to escape from the realm of Mara (i.e., kilesa vatta, round of moral defilements).
