Well, the idea is that the winning numbers are generated in the moment. That's why psychics can never tell what the numbers will be.
But it's not really about generating the right numbers, per se, but creating yourself winning the lottery, as in the Bashar video. The numbers you have bought can be the right numbers if you believe and trust it enough.
But there's difficulties with this, as people have beliefs and associations when it comes to the lottery that inhibit them from creating themselves winning it.
For instance, you may believe that there's luck involved, that someone else is pulling the numbers - you don't believe completely that you're creating it.
This is all from the Elias transcripts, so if you want to read more about it, do a search, there's a lot more info.
