There is no "right" road to follow that leads to the realization of one's immortal Self.
If we wish to be one with a celestial consciousness, capable of responding with effortless wisdom to any demand -- regardless of its nature, high or low --t hen all images of such a being must be thrown away. St. Paul provides us with the reason why we must agree to die to those parts of us that hope for a higher life to come:
"But hope that is seen is no hope at all. Who hopes for what he already has?"
The life divine, in its ceaseless revelation of creation, is inimitable; so we must be, too. To spiritually model oneself after anything or anyone -- no matter how sublime -- is imitation, and any form such imitation assumes, regardless of how sincere, is by its very nature antithetical to revelation.
The illumined poet T. S. Eliot strengthens this same finding:
"I said to my soul, be still, and wait without hope, for hope would be hope for the wrong thing; wait without love, for love would be love of the wrong thing; there is yet faith, but the faith and the love and the hope are all in the waiting. Wait without thought, for you are not ready for thought: So the darkness shall be the light, and the stillness the dancing."
The realization of one's immortal Self is inseparable from its revelation. What is timeless isn't in a time to come; it is merely hidden within passing time, much as the sky often goes unnoticed because of the clouds that sail through its vast, open spaces. This exact same relationship holds true when it comes to you and what is divine. To ask yourself, "What must I do in order to be all that I am?" amounts to something like the eye asking, "What must I do to be able to see?"
Again, the true spiritual life is incomparable; nothing comes before revelation of the living now, and nothing follows it. Dare to be -- to see just what you are in each moment revealed; give yourself to this task wholeheartedly. Your willing entrance into the whole estate of yourself is the same as entering into the unattainable life you seek.
