“My questions is when you reflect on the Dhamma, time to time, your mind wanders to the people who might have offended the Dhamma. And me being very attached to this teaching, there is a friction. Has anybody overcomed such situations.”
I have. I do not worry about all those who don’t believe in Dhamma: laws of kamma, rebirth, apayas, etc. AND how to stop future suffering (understanding the causes of suffering and getting rid of those causes).
Thinking about them can generate bad thoughts and those are bad for ONESELF. Remember that those are bad vaci sankhara too. Such thoughts do not benefit oneself OR others.
What one CAN DO is to help those who are interested in Dhamma. That is all one can do: “Attā Hi Attanō Nāthō“. One is one’s own refuge. Othrers can only help.
The only way to help those who do not pay attention (who are ignorant of Dhamma) is to do metta bhavana.
