This post will be a bit different from most of the posts on this sub but I think it could be insightful to those open to it.

Anyway when I say that everything is within you, I don't mean this in some poetic way or something, but actually. For example, when you love somebody, that feeling of love you feel doesn't come from the other person. You can't feel someone's love for you, although they can show that they love you. The love that you feel when you're "in love" comes from within you.

This applies to all our thoughts, feelings, emotions and even the world. Human beings don't actually live in the same world, though we live on the same planet. That's why it's said that "there is one earth, but billions of worlds". Once you understand this, it becomes easier to let go and also to not give a fuck because it's all in you; the frustration you feel when someone does something you don't like, the love you want to get from others and so on. It's all within you, which means nobody else is responsible for how you feel. Nobody can make you angry, sad or even happy because all these emotions are already in you. The most somebody can do is trigger them, in which case they still wouldn't be the cause of it.
