Bhagavad Geeta Chapter 3 Verses 6-7
Lord Krishna guides King Arjuna
He who, restraining the organs of action, sits thinking of
the sense-objects in mind, he of deluded understanding, is called a hypocrite.
But whoever, controlling the senses by the mind, engages himself in Karma
Yoga with the organs of action, without attachment, he excels O Arjuna.
