Even in the heart chakra (Anahata), a certain sense of superiority diminishes, and one approaches bliss, but still, spiritual superiority and general superiority seem to remain. General superiority, such as social status, occupation, and possessions, seems to persist in those layers.
In Anahata, one experiences a certain degree of love, feels relatively fulfilled, experiences a certain degree of tranquility, becomes relatively stable, and experiences a certain sense of oneness. This is quite sufficient for living in general society, but even in that layer, a sense of superiority still remains.
When one transcends the throat chakra (Vishuddha) and the ajna chakra becomes dominant, the sense of superiority almost disappears, and when one reaches the crown chakra (Sahasrara), the sense of superiority disappears.
"Disappears" may be a misleading term; it's more like when a strong light is shone, the shadow disappears. So, if the vibration temporarily drops, a certain amount of superiority may reappear. Therefore, while the expression "disappears" seems correct, it is also incorrect. However, when the focus is on the relatively high vibrational level of Sahasrara, the lower vibrational level of superiority becomes unperceivable.
The phrase "there are no high or low occupations" that I sometimes hear seems to refer to this level of vibrational awareness.
If that is the case, until one reaches that vibrational level, it seems that one can only be careful not to express it outwardly.
Spiritual superiority is relatively easier to remove, as it is a relatively new phenomenon. However, general superiority seems to be deeply rooted. Especially when one's sense of superiority is fostered by those around them, or conversely, when one is constantly berated and a sense of inferiority is instilled, it seems that it takes a long time for it to disappear from the body.
Improving something that has been ingrained for decades, or something that has been fostered, takes time. One could also say that if one is aware from a young age, one will not have to struggle.
In any case, if one becomes aware of it and improves it, one can overcome the sense of superiority. However, personally, it seems that the time required for improvement is about the same as or several times longer than the period in which the problem existed. Whether this applies generally is unknown. Some people may carry trauma even after death, so it is better to improve it early while still alive.
When comparing the length of the period during which a problem occurs and the length of time required for recovery, my personal feeling is that if you consciously try to improve, it will take a number of times longer than the period during which the problem occurred for recovery, compared to letting it resolve naturally.
Even if you manage to deal with the problem, a sense of superiority often remains deeply ingrained, and usually, all you can do is be careful not to show it. However, by raising your vibration through meditation, you can overcome it to a considerable extent at the root.
