The Ascension is a 4th.Ray Initiation.

The initiation of the Ascension enables a soul to permanently move into the spiritual realm.
Once the soul has gone through this initiation, it has no need to return to Earth in a future embodiment.
To win the Ascension a soul must meet outer and inner requirements.

The outer requirements are :–

to give its gift to humankind or to a specific group of people.
to use its creative abilities to fulfill the goals that it came here to do.
to balance all misqualified energy/ karma which the soul has created in all its lifetimes on Earth.
to experience all the desires that it came here to have.
to release all attachments to the things in the material world, so that the soul becomes desireless and therefore there is nothing that can hold the soul here on Earth.
to walk the path of personal Christhood whilst still living in the dense energies of the material realm.

The inner requirement of the Ascension is that the soul :–

must choose to permanently leave the Earth behind.
be willing to give up its earthly life and experiences.
be willing to give up its earthly identity. Why? So that the soul can win the higher sense of identity as a God-free Being who can permanetly move into the spiritual realm. This choice must be made by the soul alone.
