I honestly have no idea whether ants are conscious let alone can become enlightened. I try to treat them well but I'm not planning on teaching them to meditate any time soon :)

During "the inaccessible," assumptions about an objective or pre-existing reality fall apart as well. From within the standard materialist metaphysics it seems rather unlikely that we're special (or that meditation even does anything "transcendent" besides jiggling around some neurotransmitters).
