If you arbitrarily say hurtful words to each other, it is an exaggeration, don't justify "pure heart and soul of Buddha".
In fact, it is very rare to truly "ehold the heart of Buddha". Because people are truly kind, they are not only kind but also know how to express that kindness so that people can easily listen to and accept it. being kind and having a bad mouth is either untrained, or... lazy to learn to love.
Some people also reasoned: "I live for real, not fake like some people with a spearhead". But you, friend, living for real does not mean living roughly. If it makes others cry, then what is the point of being honest? Sometimes a gentle word saves a whole day in a bad way, while a " sincere" swearing sentence kills someone's last hope.
We still grow up with the lesson of "twering our tongue seven times before speaking", but many people do not crave to listen. Don't blame vulnerable people, but ask why you keep saying things that hurt others. And don't mistakenly think yourself too proud when "I curse that, I love". If I feel sorry for them but no one dares to get close, I should leave them in the refrigerator.
In general, it is when we use words without predicting the consequences. And "Buddha's heart sack" is often just a cute excuse to continue... tormenting others' emotions with a sharp mouth like a Japanese kitchen knife.
Therefore, before saying something " confide directly", try asking yourself: "If I hear this line from someone else, do I feel hurt?" If the answer is yes, then stop, ask for compassion like Buddha, do not say it in your mouth but just admit it.
Because Buddha does not harm animals. As for you, if you have not reached the level of leniency, then at least, don't abuse kindness to justify an uncontrolled mouth.
