The word Meta as it is used in the Lionsberg System is meant to point to the eternal, universal, ultimate, self-referential, highest order, most transcendent conception of an idea.
Therefore the Meta Intention is the highest universal overarching and uniting "Intention of intentions", that by definition contains within itself and orders all other possible intentions.
The idea of the Meta Intention is critical because it provides a framework in which to stack up and align our individual intentions, with the various intentions we participate in, with the Meta Intention that is big enough to unite All.
The Lionsberg System considers the Meta Intention to be the Intention of the Spirit of Absolute And Unconditional Love.
Or simply, Love.
