"Fundamental" means something that is basic, essential, or foundational. It's something that everything else is built on or depends on.

Lies whether they are with yourself or others will catch up to you, collapsing your world.
We build our yoga pose on a strong foundation. If you skip that, it will catch up in your body and practice.
