Excellent post @kenmelendez and I think your video & article cover the concepts of Faith & Self Development.

I personally believe that self-development eventually ends, and that it happens when a person realizes that their self (ego) is the identity that is causing all of their suffering.

This can be known directly once the self (ego) is completely eliminated, even if it is just for a few moments and is known as Self-Realization or the discovery of the no-self Self.

P.S. Selfless and no-self are not the same.

Thank you!!
