The main task of a Lightbeing is to anchor the Light, to act as a transducer of Light energies, which emanate from The Source or The Central Sun. These energies are stepped down by The Cosmic Hierarchy, the Planetary Hierarchy, The Members of The Great White Brotherhood. Then the Light energies are anchored into this planet by the Lightbeings or Starseeds. It is the second coming of the Christ in the form of the anchoring of the Christ Light or Christ Consciousness on a massive scale. Many are Cosmic technicians and work with the matrices and gridworks of this planet.
Personal ascension is an expansion of consciousness to the fifth dimension.
A self realisation and a mastery over the third plane of existence or the third dimension. There are many dimensions of consciousness. There are twenty four dimensions of consciousness all the way up to The Ultimate Source. You can imagine it as a ladder of consciousness with rungs all the way up to The Source. On the rungs are beings of all different levels of consciousness all the way up to The All That Is.
