hi @anthonyadavisii,
Belated New Year Wishes to you.
"that they have is how much they are truly in control of their vulnerabilities...."
Please read this statement carefully....
He has confirmed they can truly control, but said "....how much they are..."
We can clearly understand from that point @chbartist that the degree of control may increase or reduce......so everything is in our hands....i mean everything is in our minds!
Whether vulnerability is advantageous to us or not, it is up to us!
So if we are able to act according to the situation, i.e., if we are able to adjust this vulnerability factor, it will become an ultimate boon to our lives boon or else it will be a mere CURSE!
