You cannot earn liberation. I have not earned liberation. No one will ever earn liberation. You cannot become good enough or work hard enough or be sincere enough to deserve it. Liberation has not happened to me and it will not happen to you. Yet there is liberation. There is only ever liberation. Perfection is already here. What you are is already divine.
What is sometimes said is that the self has to die for liberation to be seen. There is a problem with the language here because “has to” implies some imperative or task. But all this means is that this is already liberation, but it cannot be seen until the self disappears, until the self dies.
If what you want is to see liberation then I hope you die soon.
