The divine stream of life : Schem, Logos, Shabda, Nama, Nada, Akash Bani, Amon, Pranava
All major religions speak about a primary streaming force or vibration or of a named force as the origin of creation. But in reality exist three versions of this stream :
1. The primary divine stream is mentioned in the 'revelation of John(22)' and in Kashmir Shaivism(para-nada) and in Radhasoami. It creates the Parabrahman and the Sadashiva. It is so high, that it would dissolve the normal soul.
2. The most common stream ist the Shabda or Pranava (Spanda) oder Vajra-Nada. It is a creation of Ishvara, the divine creator god above the Trimurti.
In the "revelation of John" we can read in chapter 22: "The angel showed me the river with the water of life which sparkles like crystal. The river flows from the throne of god and the lamb, und flows in the middle of the capital through the town. On both shores of the river grows the tree of life.... All those who are there will serve God, they will see him and HIS name will be on their forehead.... "
Therefore the Meditation on the holy name(Schem, Logos, Nama , Sabda etc.) is practized in most spiritual scools. This is also the foundation of mantra-meditations.
On the buddhic plane this river appears indirectly in form of the sounds of the spheres of the "Omkara" or BANI(Pranava).
The practices of this meditation can be found in the scools of Nada-Yoga and of Surat Sabda-Yoga(Radhasoami).
One of the Kriya-Meditations of the SRF uses this effective technique in combination with a mantram(OM,AUM). In most scools of Sant Mat and in Radhasoami it is practiced with less effect just listening into the silence and waiting for the sounds to come.
In Sikhism the meditation on Naam is practiced leaning with the arms on a wooden "T".
The tibetan gurus told their disciples not to listen to the dark sounds but to the brighter vibrations. A buddhist Nada-Meditation is here.
The Nāradaparivrājaka Upaniṣad speaks about serveral kinds of Pranava, similar to Taoism.
From H.P. Blavatsky : The Voice of silence, The secret doctrine
"Before You can put Your foot on the upper step of the ladder, the ladder of mystical tones, You must hear the voice of Your God in seven different ways :
The first is like the nightingale's sweet voice chanting a song of parting to its mate.
The second comes as the sound of a silver cymbal of the Dhyanis, awakening the twinkling stars.
The next is as the plaint melodious of the oceansprite imprisoned in its shell.
And this is followed by the chant of Vina (26).
The fifth like sound of bamboo-flute shrills in shine ear.
It changes next into a trumpet-blast.
The last vibrates like the dull rumbling of a thunder-cloud.
The seventh swallows all the other sounds. They die, and then are heard no more.
When the six (27) are slain and at the Master's feet are laid, then is the pupil merged into the ONE (28), becomes that ONE and lives therein.
Before that path is entered, thou must destroy your lunar body (29), cleanse thy mind-body(30) and make clean thy heart.
Eternal life's pure waters, clear and crystal, with the monsoon tempest's muddy torrents cannot mingle. ( A Bodhisattwa has been borne. )
In the begining, before the world was created, was HE, who is the WORD.
HE was near to GOD and in everything equal to god. From the begining he was with GOD. Through HIM everything was created; nothing was created without HIM. In all created things he was the life, and for the people HE was the light. The light shines in the darkness, and the darkness has not been able to extinguish is. (Gosple of John, 1,1-5 )
(Prajapati vai idam agre asit tasya vak dvitiya asit vak vai param brahma ) or : "In the begining was Prajapati. With HIM was VAK (the WORD), and VAK was verily the highest Brahman."(Rig Veda)
Ann.: In Hinduism the Sabda or pranava is the highest origin of the Mantras.
But very few of the western disciples in the many Sabda-Scools hear the Shabda, because such techniques without an additional mantram are rather ineffective without the initiation (VAK) of a true guru !
The "sound current" on the other side of the area of the KAL(time) is known as "SAR SHABD". However, there exist sub-vibrations of the eternal tone-current also in the area of the three Gunas (of Maya): "BANI, which exits in the area of the three Gunas, is a big network of Brahma. It holds the seeker tight in the discussion, the conclusion and the consideration in the area of the KAL(the dissolution)"; Gauri, M. 3
A similar description gives Amir Khusro(in Tazkra-i-Ghousia) :
....About these 10 Melodies the Yogin meditates, his senses become still and his mind too. With the appearance of the unlimited inner music all desires of the flesh and all deadly sins disappear. The master has his own wonderful world."
--Psalms 54:1 Help us, O God of our salvation, for the glory of Thy Name, and deliver us and purge away our sins, for Thy Name's sake!
--Psalms 79:9 Our help is in the Name of the Lord.
All these sounds are just aspects of the original stream, and meditation on "light and Sound" using a Bija-Mantram like Naam, OM or Aum can aviod these sounds and lead to the direct force of Sabda for the progressed meditator. The gnostic consciousness is a visionary consciousness, and the stream itself is no sound on the higher planes.
All that explains why the statues of many BUDDHAS have such "big and long ears" : They stand in the SHABDA, and so they really have "GOLDEN EARS".
The practice of Shaba-Meditation is the Nada-Yoga. The Nada-Bindu-Upanishad is a source of this meditation - practice.
