The state of “world bliss” in yogic philosophy is the realization that the Self is intimately related to absolutely everything, within and without. It is the experience of transcending duality and embracing all of reality. When we see aspects of ourself in any given instant, be it a mere potentiality of the Self, or a more tangible tidbit, we are able to extend compassion to others and heal the fragmentation of all manifestation. You are a mere reflection of the whole universe, and healing yourself is healing the world.
Breathe deeply, and repeat.
