gain confidence by persuading

[KLPNO]

Hello everyone,

Here is a sentence from a book:

After having acquired a firm gaze, you will gain confidence by persuading a friend to allow you to practice your gaze upon him.

Do I understand correctly that the highlighted part means "you will gain confidence if you persuade a friend to allow you to..."?

Thank you.
