Om Swami
What does the Gita say about controlling the senses?
Restraint steadies the mind
Without restraint (sanyam) the intellect cannot be steady, and unrestrained senses carry away a person's intellect like strong wind carries away a boat. The one whose senses are restrained from all sides has wisdom firmly established.
Just as a strong wind carries a boat away, so unrestrained senses carry away a person's intellect.
