The blue chakra, also known as the throat chakra, is located at the base of the throat.
Physically controls the throat and neck, arms and hands and is associated with the brachial or cervical plexus.
The endocrine gland associated with this chakra is the thyroid. The physical sense associated with the blue chakra is hearing and consequently also the organs related to this sense, the ears.
The blue chakra is associated both with aspects of expression and the ability to receive and with beliefs about the manifestation of one’s goals.
It is also associated with the process of listening to one’s intuition and the state of consciousness that one experiences when following the flow of this process.
Some call it abundance, others grace.
It is also the first level of consciousness in which one directly experiences a sense of interaction with what is defined as Higher Intelligence and the relationship with the surrounding space, one’s own space.

“Moesta et errabunda” C. Baudelaire

LXII.
“Agatha, does your heart rise up and fly,
Far from the city’s black and sordid sea
Towards a sea that’s blue as any sky,
And clear and deep as pure virginity?
Agatha, does your heart rise up and fly?

The sea, the mighty sea, consoles our labour.
What demon taught the sea with raucous verse
To choir the organ which the winds belabour
And lullaby our sorrows like a nurse?
The sea, the mighty sea, consoles our labour.

Train, bear me; take me, ship, to other climes!
Far, far! For here the mud is made of tears.
— Does Agatha’s sad heart not say, at times,
“Far from remorses, sorrows, crimes, and fears,
Train, bear me; take me, ship, to other climes”?

How distant is that perfumed paradise!
Where all is joy and love with azure crowned,
Where all one loves is truly worth the price,
And hearts in pure voluptuousness are drowned.
How distant is that perfumed paradise!

But the green paradise of childish love,
Of races, songs, and kisses, and bouquets,
Of fiddles shrilling in the hills above,
And jars of wine, and woods, and dying rays —
But the green paradise of childish love,

Innocent paradise of furtive joys,
Is it far off as India or Hong Kong?
Could it be conjured by a plaintive voice
Or animated by a silver song —
That far off paradise of furtive joys?”
