Okay this is actually a perfect eastern vs western philosophy debate hidden in a taco.
I am going to make some very broad strokes here. So no armchair quarterbacking me. I know it's way more nuanced but I'm not writing an essay on Lemmy.
In general Western philosophies always have a "goal." Your human life is to prove your worthiness. You need to look back and atone for your past mistakes. You need to look forward so you can do the right things to be worthy. It is very little about being in the now.
Eastern philosophies are much more about being aware of the moment. The past has happened it cannot be changed you should not worry about it. The future doesn't exist so there's no need to focus on it. The only thing you can affect is the very moment in time you're in and the only way to affect it is through your actions.
In this case tacos are the moment. So next time you're eating a delicious taco. Spend that moment to be one with your taco. Concentrate on the smell. Then feel the texture as you pick it up. How the various colors interact with each other. Then as you bite off some, feel the textures in your mouth and how the flavors interact. Watch yourself, be aware of every time you chew. Remember there is no past there's no future there is only tacos.
