In the video I linked to, check the moments at 2:05, 3:33, 9:04 and finally 13:15 - those are the most important parts of the video to me (although imho, the whole video is pretty important and all these concepts work together as a unit) when it comes to "letting go". The parables told at these parts and the quotes make letting go easy, for me anyway, which has been hard. It's kinda satisfying knowing things are ultimately pre-destined to a degree, and if you feel a certain type of way, it's okay to acknowledge you feel that way and rest. A non-action is an action, and allowing nature to take it's natural course is fine - that's a refreshing concept, it takes a lot of weight off one's shoulders. You don't have to be the "God" of your life, you can let things go, including labels, social constructs and "what you think you have to do", because in reality, you have one life, you should be enjoying it, you don't have to do anything you don't want to do. You should be doing things because it brings you joy. And like Taoisim also says, "if you let the opinions of others affect you, you will always be their prisoner".

2:05 - By letting go, you become free: "By letting it go, it all gets done. The world is won by those who let it go. But when you try and try, the world is beyond the winning".

3:33 - Let go of your labels if you truly want to know yourself: "He who defines himself can't know who he really is".

9:04 - Wisdom and strength come from remaining humble: "The wise man is one who knows, what he does not know". A pair of twins look the same, talk the same, belong to the same family, but one is loved, trusted and promoted by others, while the other is not. He wears nicer clothes, eats better food, and lives in a nicer home. The successful twin treats the unsuccessful twin with undisguised arrogance because he falsely believes he has earned his success, thinking "maybe there is just more in me, than there is in you".

They both meet a master, who says: "When you say that one man has more in him than another, you mean only that they are not equally gifted. The unsuccessful twin has more worth than luck. You have more luck than worth. Your success is not due to wisdom, nor is his failure due to his foolishness. Both are from Heaven and not from man. Yet you are presumptuous because you have more luck, while he is ashamed though he has more worth. Neither of you perceives that things must be as they are."

13:15 - Always go with the flow: "When nothing is done, nothing is left undone". Rather than fighting against the conditions in our lives, we should allow things to take their natural course.

Honestly, this whole entire video is great - like I said before, the reason I like it is because out of all the "philosophies" and "thought exercises" out there that tell you, "you need to let go to be free", this gives you a set of instructions and a method of letting go, that if you practice, actually works. You'll find yourself feeling much happier due to the changes manifested in your environment by your subconscious behavior due to your attitude towards the world and events. And if your environment isn't an issue, overall, you'll feel more at ease with things being as they are. I feel all of this video is quotable tbh lol.

Bonus:

11:00 - Change is inevitable, so embrace it, even if it seems uncomfortable: "New beginnings are often disguised as painful endings".
