>>3608627Your attitudes define the parameters within you are willing to have thoughts (and arguments). If you have a hateful personality you will only come up with arguments that further justify hate, if you have a loving personality you will come up with arguments that justify loving others. Perception is previous to argumentation, you cannot argue about that you do not allow yourself to perceive. Arguments come later.
People can think in three modes: logos (logic, arguments), pathos (emotion) and ethos (morals). If you only focus yourself in the logos you are completely oblivious to the framework within your thoughts are pre-programmed (ethos). One of the purposes of meditation is to re-program it, the viewpoint you are making those arguments from in the first place.
Consider the following:
https://www.accesstoinsight.org/tipitaka/an/an05/an05.057.than.htmlThe link I just gave you takes you to a discourse called "Subjects for Contemplation". In this link you are advised to contemplate frequently (to meditate in) several subjects (in this case aging, illness, death, change and causality). He advises you to do that on the grounds that the more you do it it will change your attitudes and with them your actions, and will take you to act more wisely. (The reasons why I won't tell you, you might want to read it by and give it a little of thought yourself.)
So, yes, meditating on "love" (or any other good thing for that purpose) can and will actually do something to you, as long as you do it with knowledge of what and why are you doing it. Which means taking that concept and THINKING PURPOSELY about what it means, how it relates to your experiences in your everyday life, how to apply that newfound knowledge, etc. When you are exclusively "logos" it's like you are staring at a map (words) all the day and neglecting getting familiar with the actual territory.
I hope that was helpful.
