IMO what you are looking for is how to master sung/song. Karma is a aggregation of things/energies that get in a way of getting sung/song. One can go deeper in the spirituality only with deep and specific release which is song/sung in daoist tradition. You don't remove karma, you shed it like small pieces of skin or hair while doing release/sung/song. Although in the beginning of the process, some people will need a set of precepts which basically means having an ethical approach to life (yama/niyama, commandments, and all that).
Regarding maya - this is likely to be only a mental concept. Because I can't see how maya can get in the way of releasing other bodies than conceptual/mental. If/when one stops conceptualising, there will not be maya.
