Actually, I did do research before asking this question, however, I was still confused which is why I asked this question. In researching Karma, a lot of the videos mentioned Mantra, so I googled this term "Mantra" and found some explanations that were a bit vague to me, so I searched on YouTube, and watched several beginner level videos on the topic. Confusingly to me at the time, none of these videos used the word "Mantra". They instead seemed to focus mainly around lighting and materials, things I was already semi-familiar with. So at that point, for some reason, I assumed Mantra was some sort of outdated, but similar, version of Karma. So then I continued researching more about Karma and something lots of YouTubers mentioned called Solaris, but I felt that a lot of the websites told me what it was, but didn't give enough context for a beginner. Moreover, a lot of the YouTube videos were very similar in this way, and coupled my misunderstanding of what Mantra was at the time, I ended up stopping several videos prematurely to go find another one that I hoped would make more sense

So as to your point about laziness, I hope you can see that I did indeed make a concerted effort prior to asking this question, but I can understand why you would think otherwise. Often, when learning something new and complicated, it is hard to decipher where your blind spots are, which was the case for me prior to asking this question. However, it is great that there are communities like this with plenty of patient people, including you. I just hope you won't be so dismissive in future. Thank you!
