My sense is that the mind needs time to integrate the various instructions that it receives. If a very simple, narrowly-focused instruction is coming in, that won’t take much time to integrate. If many diverse instructions are coming in, then the mind will need more time to integrate all of them.
Whether the different programs can be treated as inter-related or not will probably vary from person to person. For an actor or cabaret performer, sex appeal and wealth could be really part of the same aspect of life. So Sex/Seduction and Ecstasy of Gold might be very easy for that person to integrate even when combined. For an entrepreneurial developer of VR/educational software, learning, innovation, wealth, and business building could all be part of the same vision. So Quantum Limitless, Ecstasy of Gold, and Emperor might be easily absorbed by that person.
My sense is that if the subliminals in your playlist contribute to a unified vision, your mind will probably integrate them faster. If you’ve already invested a significant level of commitment to that vision (and better still, already made some degree of progress toward that vision), I think it will integrate the benefits even faster still.
But even if the subliminals don’t all cohesively contribute to a unified vision, I think the mind will still integrate them and respond to the various messages and instructions. It’s just that it may take a bit longer.
If a person had a super-focused, really time-urgent goal, it would probably make sense to go for the one program that is most specifically related to that goal. Many of us, in contrast, are working on more general visions that cover different parts of our lifestyles and do not need to be resolved in the shortest possible amount of time. So, it’s probably okay to have a stack that represents some of your most important priorities, and to then just give it the time to do its thing, while you also give yourself the time you need to work on and grow in those areas.
