In Jain Dharma, guide the teen with ahimsa, satya, and self-control:

• Speak calmly and without judgment.
• Tell them that feelings are natural, but in Jain life the mind should be guided by vivek and brahmacharya / restraint.
• Encourage them to not rush into attachment, obsession, or secrecy.
• If the relationship is causing confusion, distraction, or hurt, advise them to pause, reflect, and strengthen inner discipline.
• Remind them that in Jain view, attachment creates bondage, so the goal is to keep the heart peaceful and the conduct pure.
• If they are young, it is wise to focus on study, character, and spiritual growth first.

A gentle way to tell them:

“Your feelings are real, but in Jain Dharma we must act with restraint and awareness. Do not let attachment control you. Keep respect, honesty, and self-discipline foremost.”

If needed, involve a trusted parent, elder, or Jain teacher to guide them kindly.
