Its the inner voice that forces someone to follow rehat ,as outlined by sikh gurus specifically by our tenth guru...and tht inner voice comes as we read and understand gurbani regularly,our gurus teachings..
Once we start applying our gurus teachings in our life,,it will only purify our life and mind .....
I will suggest her to read and understand gurbani,,,and if she do that surely she will be having tht courage to face such problems...
Rehat maryada is important and rehat maryada is not all about hairs,,its more than that ,,to purify yours thoughts,mind and life and not to do sinful acts...
Having hairs only as rehat maryada and doing other sinful acts in life ,having all bad thoughts in mind is more sinful act than tht....
