"do not allow her to gain control over you by being beautiful and by the way she looks at you"

# in your heart

"in your thoughts"

# her beauty

"what is beautiful about her."

# capture you

"gain control over you"

# her eyelashes

"her beautiful eyes". The "eyelashes" stand for the beautiful things about her body that she uses to catch a man's attention.
