Speak gently and try to adopt euphoric and pleasant words. Using malicious and harsh words against others are offensive which will severely affect their mood.
The resultant offences are:
1) it hurts the sentient beings, which is against the refuge precepts;
2) it disrupts others’ state of mind which is against Bodhisattva percepts,
3) it leads to anger and hatred which shall destroy others’ previously accumulated virtuous roots and merits during their past infinite lives.
所以说话一定要注意,没有必要平白无故地伤害他人。
Therefore one must be mindful of his words as there is no apparent reason to hurt others’ feelings.
