GV15  啞門 (yǎ mén)

Anuradha has the shakti of राधना rAdhanA which means "speech" - we are definitely in the throat chakra area.  Could this be any clearer?

At the subtle level this point also receives the amrita, the elixir of divine consciousness dripping from sahasrara through the bindu points, through the talu chakra and down the neck.  If we are receptive, we can feel it.  I have felt this in meditation and there is no orgasm in the world that compares to it!  When sexual energy flows from the heart chakra one becomes a lunatic in love, madly in love for God, totally addicted to God.  This is a pure love, not a sexual one, one that takes us deeper into our spiritual consciousness.  It is connecting with Vishnu, the sustaining principle in the cosmos at its core.  Even with this, it is a preliminary stage for yet higher experiences of ecstasy.  So how much love can you handle?  It can be overwhelming, as St. Teresa of Avila well understood.  I think saints must be born here (not yet masters yet highly evolved).  The experience is so amazing it's hard to believe there can be higher states than this, yet there are.

अनुराधा Anuradha, Radha's perfect devotion to God as Krishna/Christ

Radha-Krishna are associated with Vishuddha (throat) chakra.  In an anthropological study:  The Place of Devotion: Sitting and Experiencing Divinity in Bengal-Vaishnavism, by Sukanya Sarbachikary the pranayama practices of the sahajiyas are focused on experiencing the inner and outer "Radha-Krishna" experience.  The whole body-temple is considered as gupta-Vrindavan. Incidentally, Vrinda is (I think) the sacred Tulsi plant - often prescribed for throat issues. These sahajiyas do the mystical practices to enable them to become one with God as Love, and (presumably) the Guru-Consciousness that is represented by Krishna:
"Only when one is blessed with divine grace are one's subtle senses able to feel Vrindavan lilas in the manas (mind-heart)."  (link)

Wikipedia states that Radha-Krishna is the deity for the throat chakra but I'd like to find a more reliable source to confirm that.  It would certainly support that GV14-Radha and GV15-Anuradha hypothesis that these have to do with the throat chakra, apart from their acupuncture/kshetram positions.

Anuradha means "the one that follows Radha" in that this nakshatra follows Radha nakshatra (GV14).  The name is simply a location marker.  To really understand Radha, we need to know the context of the scriptural love story that is the allegory for this profound spiritual experience at the throat chakra:
The journey to the Divine can be a romantic journey, a journey of the lover and the beloved, where the very journey itself becomes a joy seeking the beloved. [In] this beautiful chant, the Krishna becomes the beloved… We are not being punished by the Universe, we punish ourselves but the Universe is extremely compassionate and the moment we begin to realize that the Divine is a God of love, an ocean of love, then we become like the Gopis, we get drawn to the sweetness of the Divine and we want to go deeper and deeper. The Radha is the shakti that comes out of that space inside, that endless space of being. The Krishna represents the Source of all the beauty in the Universe. The Krishna and the Radha forever exist in unity, just like Shiva and Shakti, inseparable.
If we take the possession of the Radha (Shakti), then as an energy being we long to merge into the Beloved.  And if we take the possession of the Krishna, then we enjoy the play of the Radha, we see the energies in manifestation and we become that eternal Witness.   
However we look, from the Radha or the Krishna [perspective], it is a beautiful romance. God is a God of love, an Ocean of compassion that can draw us. The truth that comes from the lips from those who are evolved is like the Basuri.  It is the melody that comes from our inside, communicating to us. Every evolved soul who can manifest the Divine becomes like the Basuri. Let us internalize the beautiful story. It is representative of the inner space.”
Sri Vasudeva, 2013 (speaking before kirtan) 
The music of the flute "is what the Krishna Consciousness at this stage works on us.  It brings up this Divine music that draws us inside," (Sri Vasudeva).  He is speaking of that blissful state inside that is the Krishna consciousness, when our heart chakra (our love) is completely absorbed in the Divine. We become madly in love with Him - there is only Him and no other.  This is the essence of bhakti yoga.  It is a yoga (a spiritual path) can take us all the way, if we are able to get beyond the idea of separation and step into transcendence.

I have to be mindful in exploring these things that while Krishna Consciousness (which is a universal principle - same as Christ Consciousness and Guru Consciousness and Buddha Consciousness at the brow chakra) - the mythological stories about Radha and Krishna would have come later.  The deity for Anuradha afterall is Mitra, not Krishna.  Clearly though a more sophisticated reading of this area recognized the level of spiritual evolution when Kundalini reaches this point - and that is it the worship of the God or Krishna within that is being implied here.  All the outer forms of the Divine from the consciousness chakras below, now begin to dissolve as we come into a more intimate relationship with our own divinity - that God is within.

God becomes our friend on the journey

The grace of this experience is that in going through your day feeling madly in love inside, you are constantly happy, knowing your Beloved is by your side, as with Arjuna, or if you are Christian, with Jesus.  The deity for Anuradha is then, appropriately Mitra, one of Adityas of friendship and partnership, who is the divine friend.  This Mitra consciousness brings to the Anuradha native the power of worship (radhana shakti) which is the essential power of bhakti yoga.  Worship expressed in speech  ( राधना rAdhanA shakti) becomes prayer, mantra, or affirmation.   God is no longer something out there, up there, judging us, the Big Guy in the clouds.  God becomes intimate with us:
A lot of us are in this relationship with God with fear. We are afraid to call God in the way of the beloved. But when that God Consciousness comes within us, we begin to see God everywhere. We believe that God is like a friend and sometimes you can be mad with Him, playfully. Wouldn’t the Divine allow that kind of relationship? Yes, but you have to be in that place to have that relationship with the Divine. That is where the pure seeker is, the Bhakti.  
Sri Vasudeva, 2011 (speaking before kirtan) 

And who is this "God on the inside"?  As Sri Vasudeva teaches, this is the Kundalini in Her function as the Inner Guide or Guru.  This is the Divine Spouse (Shakti) seeking her Beloved Cosmic Spouse (Shiva).  This is the best "I" seeking to merge in the "We" consciousness and remain forever centered in the most expansive space inside, witnessing the grosser worlds as the collective dream that it is.  Why do you think the Navamsa divisional chart of the "Spouse" is the 9th and not the 7th?  The seventh house is the physical marriage, that procreative union that is necessary (traditionally) to produce physical children that are all the fruits represented by the Saptamsa Varga (thank you Ernst Wilhelm).  The ninth house is the house of the Guru - and that really means the Guru within, that Shakti, that Kundalini, that Holy Ghost within us who is the Spouse that we are as a soul in the human experience.

The outer Guru that the ninth house also represents, if he or she is a true self-realized being (a Sadguru), is an outer expression of the same Guru.  That's why those of us who have experienced the Guru within love the outer Guru.  It's because we recognize the Spouse within us that is manifesting in that other person.  As Sri Vasudeva says, "I am your own Self."  The proper worship of the outer guru is to honour the Inner Guru.  If the outer guru is worth their salt, they will want nothing from you but to relieve you of your ignorance of your own true being.

GV15 心 Xin "Heart" [Anuradha]
This character  you can look up here and see how it has everything to do with the beautiful feelings of Radha, of that bhakti moment when Kundalini purifies the throat area and has opened the Vishnu granthis (2nd dantien).
