Smredhi’s answer : Do you suggest out of reaction or out of response peacefully.
if you are inspiring and allowing in your approach then it is not controlling. In inspiring and allowing we feel mentally free and it is out of love and care rather than out of compulsion and ego.
When we are suggesting other out of concern and care then other also needs to feel the same rather than feeling compelled, not accepted, judged or forced by us.
In early childhood we can still use discipline with inspirations but after certain age inspirations and allowing the other person to work in his accordance works much better than controlling, pulling and pushing and morever, controlling can ruin the relationship.
Approach of inspiring and allowing can be followed as much as we are centered in ourselves.
If someone is still is with closed eyes then we all have learnt in best way with experience. Sometimes we save the person from experience but then that experience is very important for him to shine in his further journey. You only need to be with that person with love and support and maximum times everything transforms into good.
Karma which is done with peace and patience always gives sweet fruit. You need to work on yourself for this response.
You can do it yourself or take help of an expert who can guide you and give some tools and exercises which will help you to handle yourself and the other in best way.
So, this is how you can inspire him towards his best and have happy relationship also.
