In my own case, a person I love was very skeptical and afraid of gnosis. She did not want to hear anything about it, so I remained silent. Years passed. Then, one day, she asked me questions. I answered in simple ways, and short, without elaboration. Later, she wanted to read something: I gave her an introductory book. Now, some years later, she is teaching gnosis.

Be a good example: respect her will, love her, be kind. But also, do what you have to do spiritually. In this way, living by your principles, she may come to understand practically.

The main thing is: do not exert your will over her mind.
