Ignoring the "assuming..." part of the OP, I like this story from Meher Baba's discourses. Note that 'ego' is used in a technical sense meaning 'lower nature' or veil covering the truth:
There is a beautiful story of a kasturi-mriga, or musk deer, that brings out the nature of all spiritual sadhana. Once, while roaming about and frolicking among hills and dales, the kasturi-mriga was suddenly aware of an exquisitely beautiful scent, the like of which it had never known. The scent stirred the inner depths of its soul so profoundly that it determined to find the source.
So keen was its longing that notwithstanding the severity of cold or the intensity of scorching heat, by day as well as by night, the deer carried on its desperate search for the source of the sweet scent. It knew no fear or hesitation but undaunted went on its elusive search, until at last, happening to lose its foothold on a cliff, it had a precipitous fall resulting in a fatal injury. While breathing its last, the deer found that the scent that had ravished its heart and inspired all these efforts came from its own navel. This last moment of the deer's life was its happiest, and there was on its face inexpressible peace.
All spiritual sadhanas of the aspirant are like the efforts of the kasturi-mriga. The final fructification of sadhana involves the termination of the ego-life of the aspirant. At that moment there is the realization that he himself has, in a sense, been the object of all his search and endeavor. All that he suffered and enjoyed — all his risks and adventures, all his sacrifices and desperate strivings — were intended for achieving true Self-knowledge, in which he loses his limited individuality only to discover that he is really identical with God, who is in everything.
