Mind control

Dhyayato visayan pumsah sangas tesupajayate, sangat sanjayate kamah kamat krodho 'bhijayate

While contemplating the objects of the senses, a person develops attachment for them. From attachment develops desire, and from desire arises anger.

Asanshayam maha-baho mano durnigraham calam, abhyasena tu kaunteya vairagyena ca grhyate

The mind is restless and difficult to restrain, but it is subdued by practice and detachment.
