There is light inside a man of light

24 His disciples said: "Show us the place where you are, because it is necessary for us to seek it." He said to them: "Whoever has ears should hear!  There is light inside a man of light, and he shines on the whole world. If he does not shine, there is darkness."

52 His disciples said to him: "Twenty-four prophets have spoken in Israel, and all (of them) have spoken through you." He said to them, "You have disregarded the living one who is in your presence, and have spoken of the dead."

May the eternal sky acquire the form of the Earth absorbing Samsara into the empty field of absolute potential and freedom

Opening the sight

Peripheral vision
"it has generally been assumed that signals from the fovea determine the effects of vision on refractive development. However, experiments in laboratory animals demonstrate that ocular growth and emmetropization are mediated by local retinal mechanisms and that foveal vision is not essential for many vision-dependent aspects of refractive development. However, the peripheral retina, in isolation, can effectively regulate emmetropization and mediate many of the effects of vision on the eye's refractive status. Moreover, when there are conflicting visual signals between the fovea and the periphery, peripheral vision can dominate refractive development."

I was observing how I see with my eyes. I noticed that also my vision seem not know how "to open" to welcome the whole visual field. It's about awareness, it doesn't matter if the eyes are closed.
As the sight opened more, neck and shoulders followed. The dorsal-ventral wave.
And my mild myopia in the right eye is almost gone.

You continually open yourself

"This is the absolute truth. And I want you to understand one thing very clearly. Although I have encouraged you to set out in the contemplative way with simplicity and boldness, nevertheless I am certain, without doubt or fear of error, that almighty God himself, independently of all techniques, must always be the chief worker in contemplation.  It is he who must always awaken this gift in you by his grace. And what you must do is make yourself completely receptive, consenting and suffering his divine action in the depth of your spirit. Yet the passive consent and endurance you bring to this work is really a distinctively active attitude, for by the sinlessness of your desire ever reaching up to your Lord, you continually open yourself to his action. All this, however, you will learn for yourself through experience and the insight of spiritual wisdom."

"But when the joyful enthusiasm it will be abundant that it will follow you to bed at night and rise with you in the morning. It will pursue you through the day in everything you do. Moreover it will seem to occur simultaneously with that blind desire which, in the meantime, quietly grows in intensity. The enthusiasm and the desire will seem to be part of each other, so much so, that you will think it is only one desire you feel, though you will be at a loss to say just precisely what it is that you long for"
"A thousand miles would you run to speak with another who you knew really felt it, and yet when you got there, find yourself speechless."
The Cloud of Unknowing & the Book of Privy Counseling

"Questa è la verità assoluta. E voglio che tu capisca una cosa molto chiaramente. Anche se ti ho incoraggiato ad avviarti per la via della contemplazione con semplicità e franchezza, tuttavia ne sono certo, senza dubbio o timore di sbagliare, che Dio onnipotente stesso, indipendentemente da tutte le tecniche, deve essere sempre il capo nel lavoro di contemplazione. E' lui che deve sempre suscitare in te questo dono con la sua grazia. E quello che devi fare è farti completamente ricettivo, consenziente e subire la sua azione divina nella profondità del tuo spirito. Eppure il consenso e la passività che tu apporti in questo lavoro è davvero un atteggiamento spiccatamente attivo, dall'innocenza del tuo desiderio all'arrivare fino al tuo Signore, tu continuamente ti apri alla sua azione. Tutto questo, però, lo imparerai da solo attraverso l'esperienza e l'intuizione di saggezza spirituale. "

"Ma quando quel gioioso entusiasmo sarà abbondante ti seguirà a letto la sera e si alzerà con te al mattino.  Sarà con te tutto il giorno in tutto ciò che farai. Inoltre sembrerà verificarsi simultaneamente a quel desiderio cieco che, nel frattempo, cresce quietamente in intensità. L'entusiasmo e il desiderio sembreranno essere uno parte dell'altro, tanto che ti sembrerà di avere un solo desiderio, anche se non sarai in grado di trovare il modo di dire con precisione cos'è quello a cui stai anelando"
"Correresti per mille miglia per parlare con un altro che tu sai ha davvero sentito queste cose, per poi, quando arrivi​​, ritrovarti senza parole."

Suppling the brain and the body

Training in the path of the channels "helps to eliminate defects from the channels, winds and drops, making them very clear and flexible and preventing us for contracting diseases associated with them. if these three elements are supple the body as a whole will also be supple. This is because the channels, winds and drops pervade the entire body. It is very important for a meditator's body to be comfortable and flexible because this helps the mind to became clear and lucid, and a clear mind makes meditation powerful."

"The peaceful method may take slightly longer but it is a much smoother process. When the winds are brought into the central channel in this way they enter very gently and smoothly, and without the mental and physical side effects that could result from disturbing the channels, winds and drops. Those who can practice this peaceful method successfully do not need to meditate on the body as being hollow because for them there is no danger of wind or channel diseases. Je Tsongkhapa explained that the peaceful method is superior to the forceful one."

"The four places where these knots occur are four of the six major channel wheels. At each of the six major channel wheels a different number of spokes, or petals, branch off from the central channel in the same way that ribs of an umbrella branch off from the central pole."

I did not know and I could not see

By the river's dark, I wandered on
I lived my life in Babylon
And I did forget my holy song
And I had no strength in Babylon
By the river's dark, where I could not see
Who was waiting there, who was hunting me?
And he cut my lip and he cut my heart
So I could not drink from the river dark
And he covered me and I saw within
My lawless heart and my wedding ring
I did not know and I could not see
Who was waiting there, who was hunting me?
By the river's dark, I panicked on
I belonged at last to Babylon
Then he struck my heart with a deadly force
And he said, "This heart, it is not yours"
And he gave the wind, my wedding ring
And he circled us with everything

Without a guide or light than that which burned in my heart

En una noche obscura,
con ansias en amores imflamada,
¡oh dichosa uentura!
sali sin ser notada,
estando ya mi casa sosegada.

A escuras y segura,
por la secreta escala disfraçada,
¡oh dichosa uentura!
a escuras y ençelada,
estando ya mi casa sosegada.

En la noche dichosa,
en secreto, que nadie me ueya,
ni yo miraua cosa,
sin otra luz ni guia
sino la que en el coraçon ardia.

Aquesta me guiaua
mas cierto que la luz del mediodia,
adonde me esperaua
quien yo bien me sabia,
en parte donde nadie parecia.

¡Oh noche que me guiaste!
¡oh noche amable mas que el aluorada!,
¡oh noche que juntaste
amado con amada,
amada en el amado transformada!

San Juan De La Cruz

Task-negative network

"The default network is a network of brain regions that are active when the individual is not focused on the outside world and the brain is at wakeful rest. Also called the default mode network (DMN), default state network, or task-negative network (TNN), it is characterized by coherent neuronal oscillations at a rate lower than 0.1 Hz (one every ten seconds). During goal-oriented activity, the DMN is deactivated and another network, the task-positive network (TPN) is activated. It is thought that the default network corresponds to task-independent introspection, or self-referential thought, while the TPN corresponds to action, and that perhaps the TNN and TPN may be "considered elements of a single default network with anti-correlated components".
