Fear. Did Buddha teach about fear?

[samseva]

As you say, both do contain an element of fear, and I'd suggest they can contain more than just an element. An experienced commentator has rendered samvega as, "terror." It's possible that, if we don't experience it as such, we haven't contemplated enough. Similarly with ottappa if it isn't experienced intensely. In the second Maranassati Sutta, the Buddha illustrates what might be a suitable emotional tone for our practice:

Just as when a person whose turban or head was on fire would put forth extra desire, effort, diligence, endeavor, undivided mindfulness, & alertness to put out the fire on his turban or head, in the same way the monk should put forth extra desire, effort, diligence, endeavor, undivided mindfulness, & alertness for the abandoning of those very same evil, unskillful qualities. (1)

I think this draws a clear relationship between the qualities of samvega/ottappa and a very "primitive fear". If the person weren't afraid of being burned alive, he wouldn't put forth any effort. Fear can be wholesome not in the sense that it's a good emotion to indulge in, but in that it's an emotion that can spur one to positive action, and is necessary for such a purpose.

Yes, the Sutta passage is correct, but it shouldn't be taken in a pure/absolute and literal sense. It is a way of teaching to demonstrate importance and to show an aspect of something, in this case saṃvega.

To support what I am saying, the second any of the wholesome mental factors contain any form of craving, aversion or greed and hate, it is not a wholesome factor anymore. From this, even if the word 'terror' is used by an experienced commentator, it is to illustrate a point and is still an approximate labelling of a term where most of the time adding many words would be very unpractical.

To use a more practical example, if an experienced meditator were to experience high degrees of saṃvega (which would be useful and beneficial for meditation), but it would instead ressemble or be high degrees of terror, this person would be riddled with anxiety and would not be able to meditate.

All this (and similar to things you mentioned in other threads) shows the huge importance of reading and studying a number of different discourses touching on the exact same topic, but from different perspectives. This therefore allows us a more complete and precise understanding of similar teachings, which are oftentimes complex and subtle.

[SarathW]

Fear is an aspect of dosa cetasika.

I think fear is more complex than that.
I think it is more to do with the doubt about your ability.

The fear is the result of seeking protection in the conditioned. That is delusion (Moha)
This contribute to the fact that we do not see the real fear of old age, sickness and death.
People who seek protection in the unconditioned (Nibbana) may not have the fear.

[Zom]

There are things missing in abhidhamma, not only fear, but also, for example, esteem.

[SarathW]

Did you mean respect and admiration?
or Saddha and Mudhitha?
