The verdict of the Scriptures is that when man follows the senses he becomes an animal. When he is guided by the mind, he becomes a man. One who acts according to the Buddhi, becomes great among men, while the one who is guided by the Atma becomes Brahman. If you cannot follow buddhi, you should atleast follow the mind, so that you may at least keep up your human level. (ICS, p. 104)
