From Personal Growth to Oneness

On the spiritual journey, you need to work on your personal development for some time
because certain qualities and maturity are required
to overcome personal issues, patterns, and conditions.
However, there must come a time when you allow the personal to merge with the Self.
The personal still functions after that, but under the guidance of the Self.
This is the whole point of the journey: only one can remain.
The two rivers meet and flow into the ocean as one.
Then, you reach the state of non-duality.
That is oneness in practice.
That is the real meaning of “Who am I?”
