There are lots of books and videos for abundance. In 3D perspective abundance is money and fame, like ego's need to feel big. Exchange new goods and toys for some hours of feeling lucky.
In 5D perspective you have always abundance, cause you are able to see what is already there. You start to see goods and toys as tools to solve something. You realize that solving things is hearts laughter. Personally the uplift was mirrored on my bank account, caused by viewing the timelines that show the short life term of egoic buying for luckiness. I am always pointed out what is already here, the existing abundance. This turns to emotions of luck and peace. Mind cannot believe this, but when you ask higher self there is always one answer "Everything is well just in the moment'. Experience this, it's real fun.
