Benefiting others does not necessarily mean disciplining others. For example, telling others that you should not do this, what will happen if you do this, etc., etc.
Although some people have good intentions, they immediately say not to do this when others do something, etc. to discipline others.Generally speaking, there is no problem with this.
But from another perspective, this behavior should be placed in the second step, and the first step is to subdue one's own mind.
After regulating one's own mind, you will have some experiences and methods of how to regulate one's own mind, etc. After you have experience in dealing with troubles like this, when you remind others, what you say will be really powerful, others will have feelings, and will benefit.
Otherwise, if you just meddlers and overly enthusiastic, it will be difficult to benefit others if you do this.Therefore, the first step to altruism is to change yourself.
