Buddhism aims to save oneself (extinction of affliction, extinction of intellectual disability, release from reincarnation) to attaining enlightenment (leading to nirvana) by relying on Buddhism and putting Buddhist teachings into practice by oneself, and moving towards saving all sentient beings.
“Everything in this world is just bad. So don't be foolish and hope for anything, don't expect anything; it's always ruthless where nothing can come true; don't dream, give up such foolish desires, kill yourself completely, don't feel anything, ignore pain even if you're hurt, and live like a dead person”
Everything in this world is made up of causality (cause and condition), and depending on cause and effect, there are fun things, good things, bad things, and bad things. However, what is made up of cause and effect is an “sky” with no substance, and no matter how much one wants to keep that thing or thing, there is no entity anywhere that can be kept. It is as if you peel it off like a Basho leaf (leaf without a stem) and you can't find the core.
In other words, it feels like they have an illusion as if they have a mirage, and the cause is due to ignorance (fundamental ignorance), a tough obsession with truth (being trapped that it is true that there is an substance in it).
Of course, the emptiness of nothing is not absolute. If you think that way, you will become pessimistic.
Instead, the state of things and things is possible depending on cause and effect, which means that even though they exist, they do not exist because they have an entity.
Understanding this, and depending on the causal relationship, it means working on that causal relationship as something that naturally also has enlightenment and nirvana. It was Shakyamuni who showed the cause and effect for achieving enlightenment and nirvana, and it is Buddhism.
Understand that it's not a simple thing of wishing, don't expect, don't have desires, don't be attached, and it's OK to wish, have dreams, expectations, have desires, emotions, and feelings, and can't be helped even if you become attached, but all of them are “empty” with no substance at all, and are made up of causation, that is, good fortune, and work on good causality by making use of your life as a rare and thankful person That's why it's going to be something like that.
Let's work hard together.
