Affection and aversion for the objects of sense abide in the senses; let none come under the dominion of these two; they are obstructors of the path.

In plain words: Krishna says the senses naturally feel liking for some things and dislike for others. No one should let these likes and dislikes take control, because they block the spiritual path.
