Object tags allow you to clearly discern
In Hinduism an example is given: it is like separating milk from cream. It looks the same, but it is not the same. One thing is milk and another is cream. It is learning to see in order to distinguish. And, through that distinction, you distinguish: this is correct, this is wrong; this is timely, this is not; this is suitable, this is negative. And if you discern very clearly, the right and proper action takes place. Now, if your discernment is chaotic, it is understood that the subsequent action will always be totally wrong, wrong or inadequate.

One of the steps of the Zettelkasten method is to write the object tags of a note. This step consists of identifying which objects (whether real or theoretical) are present in the idea of the note and recording them using a tag (which is why it is called an object tag).
For several months, I have been using the terms “convention” and “standard” interchangeably in my Zettelkasten. Some notes had one tag and some the other. A “convention” is something similar to a “standard”, but it is not the same. In the same way that milk is not cream.
Today I finally understood the difference between these two terms and updated their usage in my Zettelkasten. Now, thanks to making an effort to identify object labels, my discernment is clearer.
