It seems I misread your explanations then. You are right in saying that "to have a liking for ~", which will be "~ga suki". It is just the label "possession of thoughts and emotions" was a bit confusing. To me "~ ga suki" does not seem to convey "possession". It seems more like expression of emotion. But, it's just the matter of labeling conventions. No big deal.
The misunderstanding might have started from here.
Did you mean "liking" is the noun by this? If that is the case, it makes sense now.

I thought you meant by this the noun marked with the particle would express conceptual/emotional possession. But, it seems you were referring the "liking" in the English sentence "I have a liking for~".

Am I correct?
YES! basically, the phrase of "a liking for" becomes the noun and the direct object of the sentance.
You can ignore the rest of this entire post now, since you understand my meaning.

Probably your teacher explained only about the case "ga + iru/aru."
1)
机の上に鉛筆があります。
Tuskue no ue ni enpitsu ga arimasu.
2)
祖国への愛があります。
Sokoku e no ai ga arimasu.
3)
明日会議があります。
Ashita kaigi ga arimasu.
Indeed, "ga" can be used in these expressions. However, "wa" also can be used.
As I already mentioned, the noun rule I posted earlier is concerned ONLY with cases where there is POSSESSION of something. All of the above examples qualify for the use of "ga" under the
EXISTENCE condition. No one/no thing has ownership of any other person/thing in any of those sentances so there's nothing to consider regarding the possession of the nouns.
1)
机の上に鉛筆はあります。
Tuskue no ue ni enpitsu wa arimasu.
Actually, according to my sensei this is incorrect grammar. She has a couple "formulas" she gave us which she is
very adamant about stressing that word order, not part of speech, is what defines the difference when someone/thing exists somewhere. Again that sentance falls under
EXISTENCE and not POSSESSION nor EVENT condition and these formulas are also strictly for sentances where the condition of EXISTANCE is concerned. The formulas are:
place ni item ga
OR you can swap the positions of the item and the place it exists in in which case formula changes to:
item wa place ni
You could probably add more information to the sentance in which you might still use ga for the pencil, even if it is stated before the place is but that would probably be for the purpose emphasis which... let's just not get into that. Keep in mind that I'm in the Introductory Japanese I class and things like clauses, multisubject, multiverb, multi-
anything-other-than-what-you-can-fix-with-a-mo sentances are far more advanced than this course covers. We're learning the basics. It's the same way for learning English, you first have to learn standard rules and get those down and then later on you find out there's certain exceeptions to those rules where that so-called rule proves false.
Example:
- "When two vowels go walking, the first one does the talking"
So the word 'goat' is pronounced go-ote not gat and not ga-ate. Only the 'o' speaks.
BUT later on we learn there's an exception to that rule when the two vowels that are walking are the vowels '
e' and '
i'. For in that case alone, we have a subset rule which actually falsifies the first rule:
- "'i' before 'e'" so the word 'pieces' is pronounced with the 'ee' sound and not 'i' nor 'ii' simply because this new rule states that regardless of pronunciation, when the vowels 'i' and 'e' are consecutive, the word is spelled with 'ie'.
BUT later still we then learn yet another subset condition of the this last rule (which is, itself a subset condition of the main rule) exists. This new subset rule is a follow-up of the last rule mentioned which goes on to say:
- "EXCEPT when sounding like 'a' as in 'neighbor' and 'weigh'.
Again the new rule negates the rule before it.
The point I'm trying to make is that, yes, there may be exception, after exception, after exception, to the conditions of the use of
ga, just as there's specific cases in English where a 'rule' does not hold true but those are, to me, at the moment, entirely irrellevant as I must
first learn the initial rules. I
can't talk about special cases to the rules if I don't know the rules to begin with. So please, just ignore the existance of exceptions to the standard. I'm needing verification of the initial set of rules
only. Throwing in examples with more advanced levels of grammar where the standard set of rules may be rendered false, at this point, is only going to confuse me.
The basics, I want
just the basics! As for tying the relation to of ga to the
adjectives/verbs of the sentence. Well put it this way, we have yet to even hear/say/see a single sentence which contains any adjective in it (we will begin that next week). So I don't have an adjective to tie it to.
And before anyone gets into any of the following matters, we have not discussed anything regarding degrees of expression (levels of 'like' 'love' 'hate' etc., we'll get to in about 3 weeks) and we won't get into counters until the end of this semester (about 7 weeks away). Te-forms? don't exist 'til Introductory Japanese II, that's next semester. Two activities/action verbs in one sentence? doesn't exist 'til Introductory Japanese II. Half the words you used in those examples... I don't even know the vocab. for.
