We seek to eliminate the ego, but if we fully eliminated the ego the result would be just sitting there, not eating, not moving seeing all that is, until you wasted away.
Doing anything is an act of the ego. The alternative path of enlightenment is to eliminate reduce the ego until, it finds it’s path towards the “Other’s Purpose.” This is helping to facilitate others becoming aware and reducing their ego.
This is about becoming a teacher. Everyone is critical because different people have different ego stories and those will relate to different people’s journey. Doctor’s might relate better to a doctor’s journey, a homeless person might relate better to another homeless person’s journey.
The secondary purpose is to inspire those you can inspire.
