About chords and consciousness

“When a man is right, his thoughts are right, active, and they are fruitful; he loses self in love, and cannot hear himself, unless he loses the chord." (Message to The Mother Church for 1900, Mary Baker Eddy, p. 3:1–4 When)

I’ve always loved this little passage about not being able to hear oneself, unless one loses the chord. What then is the chord Mrs Eddy is referring to?

We might consider that the chord  indicates the harmonious relationship  of God, Soul, with His idea, perfect man. To typify that perfect relationship as a purely harmonious musical consonance seems very natural. 

So for man to possess, or be conscious of, that chord would require unity with Truth and Love; it would require that the individual be so unselfed that he is perfectly in tune with the Christ, his thought and purpose perfectly attuned to the divine. He forgets self. He can’t hear himself, because all he hears is God’s will. Christ Jesus is our Exemplar of this type of thought-model. He "could not hear himself" , because he was so totally immersed in Spirit.  

When, on the other hand, thoughts of self or personality dominate, there’s just one tone sounding: “Me” "Me” “Me”. No chord. 

The caution being given by Mary Baker Eddy, as I see it,  is to endeavour as best we can to avoid dwelling on thoughts of self, because all we are going to hear is our own echo chamber of dissonance hollowly banging around. We can become more unselfed  by keeping our thoughts “right, active and fruitful”. 

This quote from Science and Health with Key to the Scriptures by Mary Baker Eddy (p. 576: 31) seems to capture the spirit of the sentence under consideration :

"This human sense of Deity yields to the divine sense, even as the material sense of personality yields to the incorporeal sense of God and man as the infinite Principle and infinite idea, — as one Father with His universal family, held in the gospel of Love. The Lamb's wife presents the unity of male and female as no longer two wedded individuals, but as two individual natures in one; and this compounded spiritual individuality reflects God as Father-Mother, not as a corporeal being. In this divinely united spiritual consciousness, there is no impediment to eternal bliss, — to the perfectibility of God's creation."

Could this be the chord - this "divinely united spiritual consciousness”?
