So when a soul successfully completes the given itenary it no longer needs to reincarnate and would be a so called "ascended master".This is what I understand of ascended masters and would think all great saints and prophets are ascended masters like jesus, budha, etc etc.
What is their function then ? is it similar to the angels only difference that they have incarnation experience?
dont these souls merge with the source if we started off from there?
I would like to hear more from you on this.
thanks
