About こと
In a very similar way to のは, こと is used in Japanese for nominalization (creating a noun-like phrase). However, unlike のは, which is a combination of two particles, こと is a noun. To use こと, just add it to the end of a verb in its dictionary form.
こと (or 事 in its kanji form) is a noun that is often translated as 'thing', and in this way, literally means 'the thing that is (A)' when used for nominalization.
As we can see from these examples, ない can also be used between the verb and こと, to form a 'not' statement. There are other auxiliary verbs that may be used with こと in this way, but ない is the most common.
Although this lesson discusses こと pairing with the dictionary form of verbs, it can actually pair with any standard verb form. Standard form just means anything that does not finish with the polite ます.
Fun Fact
Unlike もの (another noun used to describe 'things'), こと is a noun that is frequently used to describe things that are 'intrinsic'. This basically means things that are describable, but not necessarily always observable (feelings, conditions, events, etc.).
Caution
When a sentence (usually short) finishes with こと, it quite often has the nuance of being a rule, or command. This こと is not actually a noun, but a sentence ending particle.
こと as a particle will almost never be written in the kanji form. However, it does originate from the same word.

Hey @TurboSushi1 !
〜ている is used to convey that someone/something is in a constant state of ‘doing’ the verb it is attached to, and this こと is to nominalize verbs that comes before it.
For example, the sentence 想像することは大切なことです is translated as ‘Using your imagination is important.’, but a closer translation would be, ‘That which is to use your imagination, is important’.

Hello everyone.
I have encountered this phrase in a light novel and i struggled to understand the first part.
自分がやられて嫌なことは他人にしないようにしましょう。
I thought it would be 自分がやられる嫌なこと but the て form inside the clause before the こと was what troubled me.
Is there a grammar point for complex こと clause like this ? I’m at N1 grammar and i don’t remember having studied this but i may be wrong. I think it’s the て form just before 嫌 that i can’t seem to process.
If i understand correctly,
自分がやられる嫌なこと : You [being done disliked] things => Disliked things being done to you
自分がやられて嫌なこと : You [being done and then disliked] things => Things done to you that you disliked.
Is my comprehension correct ?
Thanks in advance.
