Premanand Maharaj Ji
Is there a limit to forgiveness, or should I forgive everything?
Forgiveness has a limit; use discernment
Forgiveness has a line, and discernment is needed to know where it falls. Where your guru is insulted, your chosen deity is criticised, or your nation or dharma is in danger, you should not say "forgiven".
In some places anger gives more fruit than forgiveness, and in some places forgiveness works. In this, discernment is needed.
