“People who have not experienced painful struggles or suffering cannot understand the hearts of others. Only if one has tasted life’s bitterness can one lead people to happiness.
To simply view your sufferings as ‘karma’ is backward-looking. We should have the attitude :
“These are the sufferings I took on for the sake of my mission. I vowed to overcome these problems through faith.”
When we understand this principal of deliberately creating the appropriate karma, our frame of mind is transformed: what we had previously viewed as destiny, we come to see as mission.
There is absolutely no way we cannot overcome sufferings that are a result of a vow that we ourselves made”
